VVLTC search tune This patch is the result of two tuning stages: 1. ~32k games at 60+0.6 th8: https://tests.stockfishchess.org/tests/view/662d9dea6115ff6764c7f817 2. ~193k games at 80+0.8 th6, based on PR #5211: https://tests.stockfishchess.org/tests/view/663587e273559a8aa857ca00. Based on extensive VVLTC tuning and testing both before and after #5211, it is observed that introduction of new extensions positively affected the search tune results.
