Simplify aspiration window code Here the main difference is that now we center aspiration window on last returned score. This allows to simplify handling of mate scores. We have done a reversed SPRT tests, where we wanted to verify if master is stronger than this patch. Long TC: master vs this patch (reverse test) LLR: -2.95 (-2.94,2.94) Total: 37992 W: 7012 L: 6920 D: 24060 bench: 4507288
