Gear Ratios

[laurb9]

I was thinking to make the driver aware of gear ratios to simplify the calculation needed from outside.

They would be represented as two numbers such as 1:64, don't know what to call them yet.

These could help with fractional rpms, for example a "fake" 100:1 ratio would make rpm=110 be an actual 1.1rpm.

Possible issues could be an overflow in the math somewhere with really high or really low ratios.
