Update default net to nn-04a843f8932e.nnue an optimization of Sergio's nn-03744f8d56d8.nnue tuning the output layer (33 parameters) on game play. WIP code to make layer parameters tunable is https://github.com/vondele/Stockfish/tree/optionOutput Optimization itself is using https://github.com/vondele/nevergrad4sf Writing of the modified net using WIP code based on the learner code https://github.com/vondele/Stockfish/tree/evalWrite Most parameters in the output layer are changed only little (~5 for int8_t). passed STC: https://tests.stockfishchess.org/tests/view/5f716f6b3b22d6afa506941a LLR: 2.94 (-2.94,2.94) {-0.25,1.25} Total: 15488 W: 1859 L: 1689 D: 11940 Ptnml(0-2): 79, 1260, 4917, 1388, 100 passed LTC: https://tests.stockfishchess.org/tests/view/5f71908e3b22d6afa506942e LLR: 2.93 (-2.94,2.94) {0.25,1.25} Total: 8728 W: 518 L: 400 D: 7810 Ptnml(0-2): 7, 338, 3556, 456, 7 closes https://github.com/official-stockfish/Stockfish/pull/3158 Bench: 3789924
