[board] Implement some castling checks on Move
...
Define some constants in Square that refer to the starting positions of the two
kings, and the target castling squares. Then implement the following methods that
use those constants to determine if a move is a castle.
- Move::is_kingside_castle()
- Move::is_queenside_castle()
- Move::is_castle()
These checks only apply to King moves, and if the king is moving from and to
specific squares.

[board] Fix a handful of linter warnings by allowing them
...
The linter also requires non-compliant formatting of the constants produced in
the coordinate_enum macro to be marked as allowed.

Reimplement Square as an enum; implement Rank and File enums
...
Replace the Square struct with an enum. This implementation is based on this one:
https://github.com/analog-hors/magic-bitboards-demo/blob/main/types/src/square.rs
This reduces a lot of code needed to construct squares, ranks, and files.

[board] Implement a BitScanner on u64
...
This struct implements an Iterator that returns the positions of the 1 bits in the u64.
BitBoard takes this iterator and maps it into Squares in the pieces() method.
This is laying the groundwork for an iterator over the pieces in a Position. 👀
