Add preview_scene script

    - This is also what powers the display code in `poolpay/display`, however, this is the original version of the script

- `test_touch.py`

    - Use `evdev` to get touch events, prints many of them (including coordinates)

- `preview_scene.py`

    - Preview a scene using a fake PyGame display
