pub fn find_magic_and_shift(
    mobility: Bitboard,
    max_shift: usize,
    min_shift: usize,
    max_tries: usize,
) -> (u64, usize, bool)

tries to find magic and shift in certain number of tries per shift for a mobility, starting from a maximum shift, going to minimum shift, returns a tuple of the found magic and a bool indicating success
