Add support for Asakuki aroma diffuser

Issue #473

- light: adjusted to accept format with rgb only (no hsv)
  I initially thought this would help to support the inconsistant 6/7
  byte format for this device, but it still needs to set the hsv when
  setting the colour, even if it can read just the rgb.
