5553bab659 [board] Teach DiagramFormatter how to highlight and mark squares
Add two BitBoard attributes to the struct that mark squares that should be marked
or highlighted.

Empty marked squares are shown with an asterisk (*). Marked squares with a piece
don't have any change of appearance. (Something I'm still thinking about.)

Highlighted squares are shown with the ANSI escape sequence for Reverse Video.

0b100d5f14 [board] Remove Flags struct, replace it with Castle and supporting structs
Encapsulate castling rights within a small module. Castle provides the API to the
rest of the board package. Rights encodes the castling rights for each player.
Parameters defines castling parameters for each player.

30188d478e [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.

c297e4cbfa [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.

90e33d1202 [board] Replace Pieces iterator with Mailbox::iter()
Mailbox can use a standard iterator because it's just a slice. So nice!

Write a test on the king move generator to verify the king can't move to a
square where it would still be in check.

b002442b42 [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.

164fe94bc0 [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.
