stepmotor: made significant changes to stepper driver

Browse Source

Fun to work on, I have maybe 3 different implementations for this one now.
Submitted version uses GPIOs only, no more PWM thus enhancing compatibility.
Fast writes and busy-wait delays ensure accuracy to a few μs when generating
the step pulses.
