Implications of customized system firmware - Photon

[mdma]

@UMD

For example, to assist with deployment issues, RGB LED changes could be caught and reflected in some other UI (say an offboard RGB LED).

For that, we have set_rgb_led_handler.

@UMD

If it doesn't take too much or your time, could you provide a list of proposed events?

I'm maintaining an event list in the issue description. I don't expect it to be complete, but continually evolving. If you have suggestions feel free to add to the issue!
