* 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
