Adafruit-circuitpython-pyoa

This release adds back compatibility for the PyPortal. Previously broken due to a dependency on `gamepadshift` module which does not exist in the PyPortal's firmware.

This release adds PyBadge/PyGamer support to the PYOA library via the inclusion of [CursorControl](https://github.com/adafruit/Adafruit_CircuitPython_CursorControl).

Release Notes
* Detects touchscreen/joystick+button hardware and instantiates the appropriate classes.
* Added dynamic button and text rescaling depending on display size (Adafruit PyGamer has a smaller rez display than the PyPortal).
* Added `SPEAKER` audio for PyGamer
* Replaced bitmap font loading with the builtin system font, terminalio, for rendering text on smaller displays.
* Updated the cave `cyoa.json` example to use less characters, split one of the larger cards in half for smaller displays.

Fonts are now stored in a fonts directory inside each game directory. This lets a game be completely self-contained.

Moved some sounds around and added a new one.

A second example adventure has been added: a cave exploration with a selection of sounds for ambiance.

A CircuitPython framework for writing choose your own adventure style applications for the PyPortal.
