* Renew the KLAP handshake session 20 minutes before we think it will expire
Currently we assumed the clocks were perfectly aligned and the handshake
session lasted 20 hours. We now add a 20 minute buffer
* use timeout cookie when available
* Add new cli command 'command' to execute arbitrary commands
This deprecates 'raw-command', which requires positional argument for module,
in favor of new 'command' that accepts '--module' option for IOT devices.
* Pull block list to the module level
* Allow raw-command and wifi without update
* Call update always but on wifi&raw-command
* Add tests
* Skip update also if device_family was defined, as device factory performs an update
* dump_devinfo improvements
* Scrub only the last three bytes for mac addresses
* Add --target to allow creating fixtures based on discovery
* Save fixtures directly to correct location, add --basedir to allow defining the location of repository root
* Add --autosave to disable prompting for saving
* Update fixtures for devices I have
* Add fixture for HS110 hw 4.0 fw 1.0.4
* Improve help strings
* Fix tests
* Update devtools README
* Default to discovery if no host/target given
* Fix connection indeterminate state on cancellation
If the task the query is running in it cancelled, we do
know the state of the connection so we must close. Previously
we would not close on BaseException which could result
in reading the previous response if the previous query was
cancelled after the request had been sent
* add test for cancellation
* Avoid linear search for emeter realtime and emeter_today
Most of the time the data we want is at the end of the
list so we now search backwards to avoid having to
scale all the data and throw most of it away
* more tweaks

This will also use the existence of energy_monitoring in the component_nego query to decide if the device has the service.
* Move emeter related functions to tapodevice
* Remove supported_modules override for now
This should be done in a separate PR, if we want to expose the available components to cli and downstreams
* Dedent extra reqs
* Move extra_reqs initialization
* Fix tests
* Do login entirely within AesTransport
* Remove login and handshake attributes from BaseTransport
* Add AesTransport tests
* Synchronise transport and protocol __init__ signatures and rename internal variables
* Update after review
- Show discovery results for unsupported devices and devices that fail to authenticate.
- Rename `--show-unsupported` to `--verbose`.
- Remove separate `--timeout` parameter from cli discovery so it's not confused with `--timeout` now added to cli command.
- Add tests.
This fixes changing the color for L530:
* If color temp is set on the device, it overrides any hue/sat settings. We override it to zero which seems to work.
* L530 does not allow None/null for brightness, so we avoid passing it on to the device.
* Add KP125M fixture. Enable tapo auth in pytest.
* authentication is not just for tapo
* Use "##MASKEDNAME##" base64 for nickname and ssid.

This refactors `Discover.connect_single` by moving device instance construction into a separate device factory module.
New `SmartDevice.connect(host, *, port, timeout, credentials, device_type)` class method replaces the functionality of `connect_single`,
and also now allows constructing device instances without relying on UDP discovery for type discovery if `device_type` parameter is set.

* Add support for the new encryption protocol
This adds support for the new TP-Link discovery and encryption
protocols. It is currently incomplete - only devices without
username and password are current supported, and single device
discovery is not implemented.
Discovery should find both old and new devices. When accessing
a device by IP the --klap option can be specified on the command
line to active the new connection protocol.

Display an error if both --alias and --host are defined to avoid ambiguous target device:
```
❯ kasa --host 123 --alias 123 state
Usage: kasa [OPTIONS] COMMAND [ARGS]...
Try 'kasa --help' for help.
Error: Use either --alias or --host, not both.
```
Also, use `click.BadOptionUsage` consistently for other errors, like when only `--username` or `--password` is given.
Several KASA devices seem to have pretty strict buffer size limitations on incoming/outgoing data transfers.
Testing on KL125-US and HL103 has shown that sending a request size larger than about ~768 bytes will immediately crash the device. Additionally, a query that generates a response larger than ~4096 bytes will crash the KL125-US. I was unable to generate such a large response to test the HL103.
The KL125-US will only return such large queries when its monthly usage stats have been populated. This means that a new bulb would work fine, but after a month of data collection the bulb would break the 4K limit and start to crash.
To work around this issue, an estimated worst-case response size is calculated before sending a request by summing up all modules estimated response size. If the estimated size is greater than the device's max_response_payload_size then the query will be split into multiple queries.
This PR implements splitting queries expected to have large responses and also removes the module 'skip list' which was a previous workaround to the crash (which worked by simply reducing the number of modules queried, which prevented the overflow) since it is no longer necessary.
This PR does not attempt to address the "input buffer size limit." Thus far this limit has not been an issue.

* pytestmark needs to be applied separately for each and every file, this fixes the tests
* use pathlib for resolving relative paths
* Skip discovery doctest on python3.7
The code is just fine, but some reason the mocking behaves differently between 3.7 and 3.8.
The latter seems to accept a discrete object for asyncio.run where the former expects a coroutine..
* Adds a transition param to set_brightness(), turn_on(), and turn_off() that specifies the duration in milliseconds that the dimmer switch will take to transition to the new state.
* Fixes bug where set_brightness(0) was allowed even though the dimmer does not support it. Now brightness values of 0 are coerced to 1 to be consistent with bulbs (which do support brightness values of 0).
* Move tests to device-type specific test files to make improvements more approachable
* protocol: remove the port parameter from query, as there are no other known ports, fix docstrings
* Revise docstrings, remove superfluous information and remove unused methods ({set,get_icon} and set_time)
* cli: indent device output to make it more easily readable when having multiple devices
* remove adjust flake8 ignores (we have no setup.py anymore)
* pyproject: include cli tool to coverage, add config for interrogate (docstring coverage)
* bulb: raise exception on color_temp error cases instead of returning zero values
* improve bulb tests, simplify conftest
* strip: rename plugs property to children and move it to smartdevice
* Optimize I/O access
A single update() will now fetch information from all interesting modules,
including the current device state and the emeter information.
In practice, this will allow dropping the number of I/O reqs per homeassistant update cycle to 1,
which is paramount at least for bulbs which are very picky about sequential accesses.
This can be further extend to other modules/methods, if needed.
Currently fetched data:
* sysinfo
* realtime, today's and this months emeter stats
New properties:
* emeter_realtime: return the most recent emeter information, update()-version of get_emeter_realtime()
* emeter_today: returning today's energy consumption
* emeter_this_month: same for this month
Other changes:
* Accessing @requires_update properties will cause SmartDeviceException if the device has not ever been update()d
* Fix __repr__ for devices that haven't been updated
* Smartbulb uses now the state data from get_sysinfo instead of separately querying the bulb service
* SmartStrip's state_information no longer lists onsince for separate plugs
* The above mentioned properties are now printed out by cli
* Simplify is_on handling for bulbs
* remove implicit updates, return device responses for actions, update README.md instructions. fixes#61
* discover dimmers properly
* fix circular import, hopefully
* add is_color to SmartDevice API
* allow changing the dimming without implicitly turning the device on
* Add tests for device type handling for discovery data, make sure new fixtures are added to categories inside conftest
* Convert to use poetry and pyproject.toml, update README
* add some resources for contributors
* minor adjustments
* ci: separate tests from linting, run using poetry
* add pytest-mock to dev requirements
* combine running tests and reporting to codecov
* generate both xml and html coverage reports
* add codecov to dev dependencies
* moves on_since property to smartdevice class, as it is not plug only
* returns None if the value is not available (some bulbs), or if the device is off
* async++, small powerstrip improvements
* use asyncclick instead of click, allows defining the commands with async def to avoid manual eventloop/asyncio.run handling
* improve powerstrip support:
* new powerstrip api: turn_{on,off}_by_{name,index} methods
* cli: fix on/off for powerstrip using the new apis
* add missing update()s for cli's hsv, led, temperature (fixes#43)
* prettyprint the received payloads when debug mode in use
* cli: debug mode can be activated now with '-d'
* update requirements_test.txt
* remove outdated click-datetime, replace click with asyncclick
* debug is a flag
* make smartstripplug to inherit the sysinfo from its parent, allows for simple access of general plug properties
* proper bound checking for index accesses, allow controlling the plug at index 0
* remove the mess of turn_{on,off}_by_{name,index}, get_plug_by_{name,index} are enough.
* adapt cli to use that
* allow changing the alias per index
* use f-strings consistently everywhere in the cli
* add tests for get_plug_by_{index,name}
* Add tests to the cli tool
* add pytest-mock
* do not ignore cli.py for coverage
* read requirements_test.txt instead of redefining reqs in tox.ini
* Add upload to codecov, first try!
* fix name of the result file
* no need to manually publish to azure devops..
* Add commands to control the wifi settings
Enables initial provisioning and changing the wifi network later on without the official app
* new api to smartdevice: wifi_scan() and wifi_join(ssid, password, keytype)
* cli: new subcommand 'wifi' with two commands: scan and join
* update readme to initial setup
* improvements based on code review, f-strings++
* Move dimmer support to its own class
SmartDimmer extends SmartPlug with brightness settings.
This will make the API of SmartPlug less confusing and will
make it simpler to downstream users to act with dimmers.
Fixes#33
* Lint & make tests pass
* Fix rebase after cache and emeter cleanups, hopefully everything went smoothly..
* oopsie, has_emeter was mistakenly included in smartplug
The cache was useful trick when the property accesses caused I/O,
which is unnecessary now as dev.update() does explicitly cache results until its called again.
* Enable Windows & OSX builds
* Add pypy for ubuntu
