LCD and Input optimizations

[me-no-dev]

• 27.24 ms to draw a frame
• better support for older PSOne controllers
• skip every other frame (60 to 30 fps for much smoother playback)
• add option to use fast vspi pins (remaps the LCD pins)

@Spritetm not liking it?

Ah, sorry, I did hear you had a bunch of optimizations done, but somehow I entirely overlooked this merge req. I'll look it over and merge.
