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
