Fix scores from reverse futility pruning This fixes futility pruning return values after recent tweaks, `eval` is guaranteed to be less than the mate-in range but it can be as low value such that the average between eval and beta can still fall in the mated-in range when beta is as low in mated range. i.e. (eval + beta) / 2 being at mated-range which can break mates.
