[board] Convert &BitBoard to BitBoard for several Board methods
...
I don't think passing by reference buys much for BitBoard. So simplify the
logic and borrowing semantics to make these easier to work with.

[board] Replace implementation of Board::piece_on_square with a simpler one
...
Now that board has a Mailbox, the implementation of this routine can be greatly
simplified. Instead of needing to iterate through all BitBoards to find the
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.
