Suspension angle sensing

Linear potentiometers appear to be the most common sensors used for suspension movement. However they are extremely expensive and susceptible to damage. The use of reworked RC servos should suffice for basic measurement. Those with additional cash reserves would be able to use linear potentiometers without code modification, just some basic recalibration.

Should be trivial to implement using four of Genboard's ADC inputs.

Original requirements will be for only two, as I can’t figure out how to place the front ones while avoiding rock damage. However there should be a provision for four.
