Entropy Gain for per-receptor NPS

[RenegadeLucien]

It was not pure NPS (NPS was included in the algorithm but only a small factor). It was more like "give each note a value based on how close it is to the next one on the next arrow/hand/overall, then sum everything and take the highest consecutive X notes, add factors for stamina/consistency/NPS"

I did a bunch of playing around with the factors and scales but I would always end up with either long streamy files being rated way too high or big spiky files being rated way too high (or both.)
