whitePromotionDistance < blackPromotionDistance - 1

[bagaturchess]

Hello,
this is a feature request for the pawns evaluation function.
In the java file https://github.com/sandermvdb/chess22k/blob/master/src/main/java/nl/s22k/chess/eval/PassedPawnEval.java there is a block:
if (whitePromotionDistance < blackPromotionDistance - 1) {
score += 350;
} else if (whitePromotionDistance > blackPromotionDistance + 1) {
score -= 350;
}
This code doesn't include the score into the endgame part of the eval, which should be not good ... I assume that in endgames it is even more important to handle these cases. Probably the ELO would be more if this is implemented. Also it is good to have a bonus of 175 for promotionDistance == 2, when the pawn cannot be stopped similar to promotionDistance == 1.
And another topic: in KPsvKPs endgames would be good to have implemented unstoppable passers logic.
