Simplify casting extension On November 16th, before the removal of the depth condition, I tried revising castling extensions to only handle castling moves, rather than moves that change castling rights generally. It appeared to be a slight Elo gain at STC but insufficient to pass [0, 4] (+0.5 Elo), but what I overlooked was that it made pos.can_castle(us) irrelevant and should have been a simplification. Recent discussion with @Chess13234 and Michael Chaly (@Vizvezdenec) inspired me to take a second look, and the simplification continues to pass when rebased on the current master. This replaces two conditions with one, because type_of(move) == CASTLING implies pos.can_castle(Us), allowing us to remove the latter condition.
