Support external pull ups? #15

Open caternuson opened 2 years ago

Library currently enables internal pull ups: https://github.com/adafruit/Adafruit_CircuitPython_MatrixKeypad/blob/71feb81d9d2b90aa8b5ab2f4eb08cbcdd4a79eae/adafruit_matrixkeypad.py#L63 but not all boards have internal pulls.

Could surround with try/except and just silently consume the exception? Sort of like "enable internal pulls if they exist".
