Update protocol to support other bulb types

[mjg59]

The current implementation only supports RGB+W bulbs, but the protocol supports multiple other types. Add support for identifying the controller based on its ID byte, and add a real rgbw command for devices that handle it. In addition, there's some amount of support for devices that handle warm+cold white - this is entirely untested and unlikely to work well.
