Smile: various changes/improvements

Changes:

• Provide cooling_state and heating_state as binary_sensors, show cooling_state only when cooling is present
• Clean up gw_data, e.g. remove single_master_thermostat key

Smile: small improvements

• Move schedule debug-message to the correct position
• Code quality fixes

Adding measurements

Adding measurements:

• Expose mac-addresses for network and zigbee devices
• Expose min/max thermostat (and heater) values and resolution (step in HA)
• Changed mac-addresses in userdata/fixtures to be obfuscated but unique

(v0.16.3: implement typing hints)

Generic and Stretch

• As per Core deprecation of python 3.8, removed CI/CD testing and bumped pypi to 3.9 and production
• Add support for Stretch with fw 2.7.18

Smile - various updates and fixes

• BREAKING: Change active device detection, detect both OpenTherm (replace Auxiliary) and OnOff (new) heating and cooling devices.
• Stretch: base detection on the always present Stick
• Add Adam v3.6.x (beta) and Anna firmware 4.2 support (representation and switching on/off of a schedule has changed)
• Anna: Fix cooling_active prediction
• Schedules: always show available_schemas and selected_schema, also with "None" available and/or selected
• Cleanup and optimize code
• Adapt and improve testcode

Smile - Change output format, allowing full use of Core DataUpdateCoordintor in plugwise(-beta)

• Change from list- to dict-format for binary_sensors, sensors and switches
• Provide gateway-devices for Legacy Anna and Stretch
• Code-optimizations

Smile - Improve implementation of cooling-function-detection

• Anna: add two sensors related to automatic switching between heating and cooling and add a heating/cooling mode active indication
• Adam: also provide a heating/cooling mode active indication
• Fxing issue #171
• Improved dependency handling (@dependabot)

Smile - Various fixes and improvements

• Adam: collect control_state from master thermostats, allows showing the thermostat state as on the Plugwise App
• Adam: collect allowed_modes and look for cooling, indicating cooling capability being available
• Optimize code: use _all_appliances() once instead of 3 times, by updating/changing single_master_thermostat(),
• Protect several more variables,
• Change/improve how illuminance and outdoor_temperature are obtained,
• Use walrus operator where applicable,
• Various small code improvements,
• Add and adapt testcode
• Add testing for python 3.10, improve dependencies (github workflow)
• Bump aiohttp to 3.8.1, remove fixed dependencies

Smile - Bugfix: handle removed thermostats

• Recognize when a thermostat has been removed from a zone and don't show it in Core
• Rename Group Switch to Switchgroup, remove vendor name

Implement possible fix for HA Core issue #59711

Also contains the changes from the not released versions:
v0.15.0 - Smile: remove all HA Core related-information from the provided output
v0.15.1 - Smile: Dependency update (aiohttp 3.8.0) and aligning other HA Core dependencies
