* 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
* 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
* 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* remove outdated click-datetime, replace click with asyncclick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..
