Allow individual control of LEDs

[sowbug]

The hardware has the capability of individual LED control (not just the RGB composition, but each lamp assembly). Please pipe that capability through to the protocol/tools.

I went ahead and made a patch here to support it
samccone@98ec349

This change however is somewhat breaking to the API as old 3 byte calls will now set no colors.
Thoughts? (if we do not care about backwards compat happy to open a PR with the existing code).

Thanks!

Have you tested this with the web app? I don't seen an update to the JavaScript code.

If we have to update the protocol for this we could bump the device version (bcdDevice in the descriptor) so that the app can detect it and send the right command.

Oh I made a new webapp locally that does a few extra things, if you are OK with this patch I can update the existing webapp to use this new protocol.
