Clarify the mapping of files to queenside Author: @nickpelling We replace in the code the obscure expressions mapping files ABCDEFGH to ABCDDCBA by an explicite call to an auxiliary function : old: f = min(f, ~f) new: f = map_to_queenside(f) We used the Golbolt web site (https://godbolt.org) to find the optimal code for the auxiliary function. STC: LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 30292 W: 6756 L: 6651 D: 16885 http://tests.stockfishchess.org/tests/view/5d8676720ebc5971531d6aa1 No functional change
