Change definition of between_bb() We remark that in current master, most of our use cases for between_bb() can be optimized if the second parameter of the function is added to the segment. So we change the definition of between_bb(s1, s2) such that it excludes s1 but includes s2. We also use a precomputed array for between_bb() for another small speed gain (see https://tests.stockfishchess.org/tests/view/604d09f72433018de7a389fb).
