    bugfix: clock_recovery tag offsets are drifting over time
    
    Allow enable_update_rate() so that relative rate is recalculated during
    each call to work. Currently tag offsets at the output drift over time.
    This fix is already applied in msk_timing_recovery_cc but is missing
    from clock_recovery_mm.
    
    See discussion about enable_update_rate:
