Raise exceptions before the gamepad_singleton is created.
Also, use mp_raise for creating the exceptions.

Radomir Dopieralski 52d05bbc37 Cache pullup state in gamepad
Don't check the pin's pull direction on every tick, instead cache it
at the beginning. Also avoid a "can't get pull of output pin" error
when one of the pins passed is in output mode.

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 1c97b7f4df Gracefully reset the gamepad module
If a soft reset happens while the gamepad module is scanning for button
presses, there is a moment when the pins get de-initialized, but the
gamepad module is still trying to read them, which ends in a crash.
We can avoid it by disabling scanning on reset.

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.
