* [lifx] Add channels for controlling absolute color temperature in Kelvin

Adds an 'abstemperature' channel to all Thing Types for controlling the absolute color temperature in Kelvin.
MultiZone lights also have 'abstemperaturezone' channels that allow for controlling the color temperature of a zone in Kelvin.
These channels make it easier to use the same color temperature with lights that have a different color temperature range.
Furthermore the channel type tags have been updated which simplifies using the generated items with the semantic model.
