When the error count is cleared, the cumulative deltas as well as the segment lenght which is kept inside the stepper isr need to be reset. Introduce a helper function fsensor_reset_err_cnt to clear all the required variables in one place which can be used in most cases (the only exceptions being quality measument). Introduce a new function st_reset_fsensor to also clear the segment lenght within the isr.
