stepcompress: Implement a step+dir+step filter

Browse source 
Some stepper motor drivers do not respond well to rapid "step +
direction change + step" events.  In particular, it is believed this
can cause "over current" events on the tmc2208 drivers when they are
in "stealthchop" mode.  Detect these events and remove them from the
generated step times.
