Reduced code size by:

- removing WS2812FX::setMode()
- removing WS2812FX::setColor()
- removing floating point in transition
- color handling modification in set.cpp
- replaced uint8_t with unsigned in function parameters
- inlined WS2812FX::isUpdating()
- (MAY BE BREAKING) alexa & smartnest update
