Limit depth after extensions to avoid asserts. currently extensions can cause depth to exceed MAX_PLY. This triggers the assert near line 542 in search when running a binary compiled with `debug=yes` on a testcase like: ``` position fen 7K/P1p1p1p1/2P1P1Pk/6pP/3p2P1/1P6/3P4/8 w - - 0 1 go nodes 1000000 ``` passed STC https://tests.stockfishchess.org/tests/view/6668a56a602682471b064c8d LLR: 2.93 (-2.94,2.94) <-1.75,0.25> Total: 143936 W: 37338 L: 37238 D: 69360 Ptnml(0-2): 514, 16335, 38149, 16477, 493 closes https://github.com/official-stockfish/Stockfish/pull/5383 Bench: 1160467
