Fruit Jam Two Gamepad Demo

This is my third iteration on CircuitPython USB host gamepad tester. This time it does two game controllers with asyncio instead of just one. The code should be more readable too. There's a boot keyboard to gamepad mapper. And, I devised a janky-but-serviceable unplug detection heuristic that works reasonably well.

Board and CircuitPython Version

I wrote and tested this on a Fruit Jam rev D (production) board with CircuitPython version 10.0.0-beta.2.
