Merge static history into main history, thus simplifying and reducing the memory footprint. I believe using static diff for better move ordering is more suited for low depths, so restrict writing to low depths. Todo: probably the condition for writing can be simplified LTC: LLR: 2.95 (-2.94,2.94) {-0.75,0.25} Total: 18752 W: 768 L: 705 D: 17279 Ptnml(0-2): 7, 635, 8034, 688, 12 https://tests.stockfishchess.org/tests/view/5fd631791ac169120188859e STC: LLR: 2.95 (-2.94,2.94) {-1.25,0.25} Total: 36504 W: 3380 L: 3313 D: 29811 Ptnml(0-2): 116, 2667, 12645, 2682, 142 https://tests.stockfishchess.org/tests/view/5fd5ed861ac1691201888569 closes https://github.com/official-stockfish/Stockfish/pull/3262 bench: 4018036
