[expolorer] Add two new commands for showing available moves and sight of a piece on a square

[position] Move make_move to its own module: position::make_move
...
Rework sight.rs and add a new module, movement.rs, to calculate piece sight and
movement. I discovered during this process that "sight" and "movement" are different
because pawns (in particular) can move in ways that don't follow their sight lines.
The routines in the movement module account for this, but also pass through to the
sight routines for other pieces.

[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.

[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.

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.
