Standardize types to uint8_t
Trying to make things a little nicer class-wise
Further class-level refactoring, yay!
De-duping fillStatus, also fixing (I think) N64 axes

Overzealously made unsigned integers, I believe
Switching to multicontroller
Setting up submodule again, and revising message
Using new axis method
Testing autodetect for NES/SNES
Some more fun detection stuff
Adding printMsg method to make Serial output less obnoxious
Refactoring further, adding a wrapper for detect_controllers
Implement new, simpler SNES/NES detection.

Also move N64 port restoration out to safe_detect_controllers
And redefine joystick mapping (inverted for now)
TODO: Figure out why USB stuff isn't working for later joysticks
