/**
* Filtering out noise on endstops requires a delayed decision. Let's assume, due to noise,
* that 50% of endstop signal samples are good and 50% are bad (assuming normal distribution
* of random noise). Then the first sample has a 50% chance to be good or bad. The 2nd sample
* also has a 50% chance to be good or bad. The chances of 2 samples both being bad becomes
* 50% of 50%, or 25%. That was the previous implementation of Marlin endstop handling. It
* reduces chances of bad readings in half, at the cost of 1 extra sample period, but chances
* still exist. The only way to reduce them further is to increase the number of samples.
* To reduce the chance to 1% (1/128th) requires 7 samples (adding 7ms of delay).
