Radomir Dopieralski 280374fa63 Respect pin's pull in gamepad
While it is traditional to have buttons on pins that are pulled up, and
have the button connect them to the ground, some CircuitPython boards
(notably the CPX) have the button pins pulled low and the button
connects them to VCC.

This patch makes the gamepad only change the pin's pull if it wasn't
already set when passed to the constructor, and also makes it consider
a button pressed when its value is the opposite of its pull.

Radomir Dopieralski f4981677b0 Add a `gamepad` module for handling buttons in the background. (#295)
The `GamePad` singleton monitors buttons in the background to make sure a button press is never missed and debouncing happens consistently.
