Limit double extensions Double extensions can lead to search explosions, for specific positions. Currently, however, these double extensions are worth about 10Elo and cannot be removed. This patch instead limits the number of double extensions given to a maximum of 3. This fixes https://github.com/official-stockfish/Stockfish/issues/3532 where the following testcase was shown to be problematic: ``` uci setoption name Hash value 4 setoption name Contempt value 0 ucinewgame position fen 8/Pk6/8/1p6/8/P1K5/8/6B1 w - - 37 130 go depth 20 ``` passed STC: https://tests.stockfishchess.org/tests/view/60c13161457376eb8bcaaa0f LLR: 2.95 (-2.94,2.94) <-2.50,0.50> Total: 73256 W: 6114 L: 6062 D: 61080 Ptnml(0-2): 222, 4912, 26306, 4968, 220 passed LTC: https://tests.stockfishchess.org/tests/view/60c196fb457376eb8bcaaa6b LLR: 2.94 (-2.94,2.94) <-2.50,0.50> Total: 166440 W: 5559 L: 5594 D: 155287 Ptnml(0-2): 106, 4921, 73197, 4894, 102 closes https://github.com/official-stockfish/Stockfish/pull/3544 Bench: 5067605
