OMEGA REFACTOR! Perf grind basically complete.

Resolves #70, Resolves #67

Still needs some regression testing in general, and a definite
regression is that rotary encoders are no longer (for the immediate time
being) supported.

Moves to a much simpler internal state tracking system, and FAR lighter
matrix scan.

Removes MicroPython support entirely.
