Revert "Rook PSQT Tuned" This reverts the previous commit. The PSQT changes in this previous commit originated from tests against quite an old version of master which did not include the other PSQT changes of 474d133 for the other pieces, and there might be some unknown interactions between the PSQT tables. So we made a non-regression test of the last commit against the last-but-one commit. This test failed, leading to the revert decision. Failed non-regression test: LLR: -2.96 (-2.94,2.94) [-3.00,1.00] Total: 95536 W: 15047 L: 15347 D: 65142 http://tests.stockfishchess.org/tests/view/5dc0ba1d0ebc5904493b0112 Closes https://github.com/official-stockfish/Stockfish/pull/2395 Bench: 4362323
