Whenever a stepper driver or a heater becomes active, it is desirable to turn on a fan cooling the associated parts on the controller board. This module implements such a fan that turns on whenever a stepper or specified heater turns on, decelerates to a configurable speed when all of the watched parts turn off, and returns to an off-speed, when a user-defined timeout is met.
