flux++

Home Assistant custom component to let coloured lights folow the day's and circadian rythm

This is heavily based on the original Flux component in Homeassistant: https://home-assistant.io/components/switch.flux/

Improvements:

Lights that have their color changed manually will not be updated
New service 'force_update' to have all lights in the Flux++ switch which are turned on participate in the future updates again
New functionality to listen for newly turned on slights that are part of the Flux++ switch. Newly turned on lights will be updated to the flux color and participate in future updates
New conf parameter init_on_turn_on to define if newly turned on lights shall participate and be reset to the flux color or not
It is now possible to call the 'force_update' service specifying one or more entity_ids of the lights that should be updated. If no entities are given, all lights in the flux switch will be updated
