Halve PSQT row data Use symmetry along vertical middle axis of the board to reduce the number of parameters. For instance psqt value of SQ_A5 == SQ_A4 and value of SQ_F8 == SQ_F1. This is always true, at least until now nobody came in with an asymmetric psqt table that worked. Original patch by Lucas. No functional change.
