itersolve: Implement a step+dir+step filter
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.
