Library Request: Matrix Keypad

[sommersoft]

A member on Discord was asking about using a Matrix Keypad with CircuitPython, similar to the Adafruit Membrane 3x4 Matrix Keypad (PID: 419).

• The Adafruit product page references this Arduino library to use with it: Keypad Library for Arduino
• The GitHub repo for the Arduino library is here: Keypad
  • It is licensed under GNU GPL, so be sure to include that license information.

I wonder if we could extend the gamepad library to support matrices.

I wonder if it won't be a little confusing to have to use a library named gamepad for key matrices, maybe it would be better to keep the Gamepad class but rename the library and add the Keypad class in that library. Both classes are pretty close in functionality so they would reuse a lot of the code, like the key scanning and the timer tick stuff.

hey i need to make one anyways, but it'd be in pure python - so you have to scan it whenever you wanna use
