* Make aiolifx modules easily available
* Use aiolifx features_map for deciding bulb features
Also move the feature detection out of Light so it is available even
during the initial detection.
* Move each LIFX light type to a separate class
* Simplify AwaitAioLIFX
This has become possible with recent aiolifx that calls the callback even
when a message is lost.
Now the wrapper can be used also before a Light is added though the register
callback then has to become a coroutine.
* Refactor send_color
* Add support for multizone
This lets lifx_set_state work on individual zones.
Also update to aiolifx_effects 0.1.1 that restores the state for individual
zones.
