Add coolix climate ❄ 🔥 (#521)

* Lint

* add coolix climate ❄ 🔥

* Fixes

* Reviewed

* Fix for dev

ClimateDevice was renamed to Climate

* Remove stale method

* Lint

* Initialize target temperature, avoid NAN value

* Use clamp and round value

* Set to verbose message

Not really relevant to the user

* Remove constructor

Name is now set in climate.register_climate - saves integrations from having to declare a constructor

* Fix, add test
