Adjust NNUE usage based on number of pawns in position The idea of this patch is that positions are usually more complex and hard to evaluate even if there are more pawns. This patch adjusts NNUE threshold usage depending on number of pawns in position, if pawn count is <3 we use the classical evaluation more often, for pawn count = 3 patch the is non-functional, with pawn count > 3 NNUE evaluation is used more often. passed STC LLR: 2.96 (-2.94,2.94) {-0.50,1.50} Total: 36520 W: 5011 L: 4823 D: 26686 Ptnml(0-2): 299, 3482, 10548, 3594, 337 passed LTC LLR: 2.98 (-2.94,2.94) {0.25,1.75} Total: 39272 W: 2630 L: 2433 D: 34209 Ptnml(0-2): 53, 2066, 15218, 2229, 70 closes bench 4084753
