Fixes#512
## Description of change
Fix digital wailing not being recognized consistently.
Also address the fact that wailing was completely broken when lefty mode
was on. This requires a new option that the user needs to check off in
the configurator since we can't magically guess if the user is holding
the guitar in lefty mode.
- [x] fix downward wail
- [x] digital lefty mode
- [x] implement all of this for arena model i/o
- [x] test dx cab 2p
- [x] lefty toggle in overlay
- [x] fix analog not working for 2p guitar
- [ ] analog lefty mode?
## Testing
Checked GW and GW Delta

## Description of change
Apply SOCD cleaner algorithm to deal with the case where both
counter-clockwise and clockwise buttons are pressed at the same time.
In SDVX, default algorithm is to prefer the most recently pressed
direction. This is better for dealing with slams in rapid succession,
for example, as you don't have to completely let go of one direction to
hit the other now.
In IIDX, default algorithm is neutral (same behavior as before). Using
last or first algorithm results in double scratches which means you'll
likely end up with an excessive poor after hitting a scratch, so neutral
is actually beneficial. Besides, if you are serious about playing on the
keyboard, you should be using `TT +/-` and `TT +/- Alternate`.
## Testing
Tested SDVX 3, EG (old cab), EG valk cab modes, IIDX 24, 27, 33
