Chess engine: Cheng 4.44
Author - Martin Sedlak
v.4.44:
NN switched from floats to fixed point - now eval/bench is deterministic again
NN topo changed to 736-224-1 (performance)
switched from leaky relu to plain relu (performance)
NN cache incremental updates (performance)
NN outputs scaled pawn scores instead of win prob (fixed oscillations at high evals) - thanks Jay
avx2 binaries provided for x64 (the preferred ones to be tested, ~20% faster)
minor bugfixes
