Tweak and update the WDL model This PR updates the internal WDL model, using data from 2.5M games played by SF-dev (3c62ad7). Note that the normalizing constant has increased from 329 to 368. Changes to the fitting procedure: * the value for --materialMin was increased from 10 to 17: including data with less material leads to less accuracy for larger material count values * the data was filtered to only include single thread LTC games at 60+0.6 * the data was filtered to only include games from master against patches that are (approximatively) within 5 nElo of master For more information and plots of the model see PR#5309 closes https://github.com/official-stockfish/Stockfish/pull/5309 No functional change
