Use int16_t in History values Reduces memory footprint by ~1.2MB (per thread). Strong pressure: small but mesurable gain LLR: 2.96 (-2.94,2.94) [0.00,4.00] Total: 258430 W: 46977 L: 45943 D: 165510 Low pressure: no regression LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 73542 W: 13058 L: 13026 D: 47458 Strong pressure + LTC: elo gain confirmed LLR: 2.96 (-2.94,2.94) [0.00,4.00] Total: 31489 W: 4532 L: 4295 D: 22662 Tested for crashing on overflow and after 70K games at STC we have only 4 time losses, possible candidate for an overflow. No functional change.
