Introduce Multi-Cut This was inspired after reading about [Multi-Cut](https://www.chessprogramming.org/Multi-Cut). We now do non-singular cut node pruning. The idea is to prune when we have a "backup plan" in case our expected fail high node does not fail high on the ttMove. For singular extensions, we do a search on all other moves but the ttMove. If this fails high on our original beta, this means that both the ttMove, as well as at least one other move was proven to fail high on a lower depth search. We then assume that one of these moves will work on a higher depth and prune.
