Implement a move generator that emits moves for the king(s) of a particular color.
There will, of course, only ever be one king per side in any valid board, but
this iterator can (in theory) handle multiple kings on the board. This iterator
is almost entirely copypasta of the SliderMoveGenerator. The major difference is
castling.
Castle moves are emitted by a helper CastleIterator type. This struct collects
information about whether the given color can castle on each side of the board
and then emits moves for each side, if indicated.
Do some light refactoring of the castle-related methods on Board to accommodate
this move generator. Remove the dependency on internal state and rename the
"can_castle" method to color_can_castle.
In order to facilitate creating castling moves without relying on Board, remove
the origin and target squares from the encoded castling move. Code that makes
a castling move already looks up castling parameters to move the king and rook to
the right squares, so encoding those squares was redundant. This change
necessitated some updates to position.
Lastly, bring in a handful of unit tests courtesy of Claude. Apparently, it's my
new best coding friend. 🙃
