Namco 6-speed Gearbox device
Used in Ridge Racer deluxe cabinet, Ace Driver and Driver's Eyes
User side gear scheme:

Being a mechanical part there are currently two methods hooked up,
emulated and natural.
First one just uses whatever is read in the inputs, second one
simulates clutch lock as in a real car.
TODO:
- check clutch lock via real HW, and get a way to lock current gear via
MAME's input system;
- Custom part #;
- gear output for artwork system;
