Add CursorControl for non-touchscreen hardware and fixes for smaller rez. displays

[brentru]

This pull request adds Cursor + Joystick compatibility to PYOA using Adafruit_CursorControl. This is useful for people creating games using PYOA and the Adafruit PyGamer/PyBadge.

Changes:

• 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.

Examples:

• Updated the cave cyoa.json example to use less characters, split one of the larger cards in half for smaller displays.
