Drive status lights off a coprocessor #436
Description
This will be a fair bit of effort but worthwhile.
Addressable LEDs aren't implemented for SystemCore (yet)- a significant chunk of our loop time is spent in our status lights (because the RobotPy bindings for AddressableLED aren't great)
An option could be to run the addressable LED strip off a Pi Pico. There's a variety of different ways to communicate with such a setup. The least wiring would involve USB; probably the easiest would be to do serial over USB.
Bonus points for wiring the climber switches to this coprocessor (see #431 for context).
