Fruitjam Match3: Improve mouse compatibility

[RetiredWizard]

When some mice, including the inexpensive mouse from the Adafruit shop, were used with the Match3 game, mouse movement was restricted to the X axis only and that motion was controlled by moving the mouse in the Y direction.

For some reason these mice were reading data buffers of length 8 but apparently have the data format of a 4 byte buffer read.

This PR adds logic to check 8 byte buffer reads and see if the first 50 reads from the mouse show exactly 0 movement in the Y direction. If it does, the mouse is assume to be supplying the buffer data in the 4 byte format.

The read timeout was also increased from 10 to 20 milliseconds since the 10 mSec was apparently too fast for the Adafruit mouse I was testing with.

I tested with the Adafruit Mouse as well as a cheap Logitech gaming mouse and they both worked well with these changes.

For the mice that need the data format change, the 50 reads takes a couple seconds so the mouse initially is stuck just moving left and right but once the format switches it has normal motion control.

When a game was completed the Play again option wasn't working on the Fruit Jam because the default folder was reset to the root. I added a try/except block to catch that case and change the directory to the fruit jam default folder for the game.

Thank you for the fixes!

This looks good to me. I tested successfully with the cheap USB mouse from store and confirmed the issue is fixed by this change.
