Parameters defines castling parameters for each player.

[board] Convert &BitBoard to BitBoard for several Board methods

[board] Replace implementation of Board::piece_on_square with a simpler one

occupied square, just consult the mailbox.

[board] Implement a custom PartialEq on Position
...
We don't need to compare cached data. The load-bearing parts of a Position are:
player to move, position of all pieces, flags, and en passant status.
Inspiration for this implementation came from the FEN spec. It specifies all
these in the string.

[board] Implement danger squares for the current player
...
This concept comes from [1]. Danger squares are the squares a king cannot move to
because it would permit the opposing player to capture the king on their next
turn.
