InputOverlay class

Builds GestureDetectors for each square on the board, handling some common gestures such as right clicks, long presses etc. Doesn't include everything that GestureDetector supports because it has literally 60+ parameters. It's easy enough to add more if you need them, and if you think one is a common enough use case, feel free to make a PR.

Note that this can't support onTap because it will interfere with the standard piece drag behaviour. Also note that gestures like long press will make tap responses on the pieces and squares take longer to respond as the gestures have to go through this first.
