PlayRing updated to PlayDate OS 2.0

Since the OS 2.0 is out now I figure it's time to release what I've done since 1.1. I was originally planning to attempt changing the time you have to hold B to cancel the selection (1 second just feels too long) and add some sort of key repeat but that's apparently not so simple.

1.2

• Added icon for PlayDate OS version 2.0
• Added sounds
• While selecting orbs you can go back with the d-pad as well as the B button.
