Allow for removal of hysteresis on 4x encoders (#13698)

* Remove hysteresis on 4x encoders

Sometimes, controller skips encoder pulses and when it returns to default position, the encoder_pulses variable isn't equals 0. And when I turn encoder in opposite direciton, it skips first click becase of encoder_pulses crosses zero. To prevent this, I add the ENCODER_DEFAULT_POS constant, and reset encoder_pulses into 0 when the state variable equals ENCODER_DEFAULT_POS.
