Add spinning wheel subsystem for Beetle #7
Description
A motorized wheel that can spin at different speeds.
The motor is a REV Robotics NEO brushless motor controlled by a Spark Max motor controller connected on CAN ID TBD (check beetle canbus eventually).
Wheel controls:
The wheel speed should be controlled by the left and right triggers.
Left trigger = spin the wheel counterclockwise (speed corresponding to trigger)
Right trigger = spin the wheel clockwise (speed corresponding to trigger)
If both triggers pressed, prefer the right trigger and ignore the left.
