Variable null-move value based reduction
Instead of a fixed reduction of ONE_PLY, now
Null move dynamic reduction based on value can
grow larger in case we are above beta of a value
much higher then PawnValueMg.
Note that now an eval returning VALUE_KNOWN_WIN
makes null search to drop in qsearch.
Passed both short TC:
LLR: 2.95 (-2.94,2.94) [-1.50,4.50]
Total: 26141 W: 4871 L: 4699 D: 16571
And long TC:
