Update custom driver implementation with encapsulated RGBMatrixDriver

[ty-porter]

Replaces this temporary spike branch (https://github.com/MLB-LED-Scoreboard/mlb-led-scoreboard/tree/fps-counter)

New driver implementation includes display overlay or log format FPS counter

Seems like a nice clean up -- I think this needs a new addition to install.sh and requirements.txt, right?

I think the installer is fine if you are referring to the --emulator-only flag, it's a convenience flag for skipping installation with sudo and not installing the hardware matrix driver

Requirements updated, replaced emulator with driver and appropriate stable version:

Going to close this, the driver lib I wrote works great with the emulator but the extra features break the hardware implementation. That's more work than I want to resolve at the moment
