829d9af52c [board] Fix some bugs in the starting position
Turns out I was doing the starting position really wrong. In an upcoming commit,
I will implement FEN output for Positions. While doing that work, I found several
issues that were causing the output of the FEN formatter to return garbage.

Implement a handful of unit tests to track down the errors.

Rename Shape::_ascii_representation() → Shape::to_ascii.
Implement to_ascii() on Piece.

3c699b0b3d [board] Remove the intermediate String when building a diagram representation of a Position
Also ignore the tests in position::diagram_formatter::tests. These don't assert
anything; they're just there for visual spot check.

72316ad5f5 [board] Write a bunch of tests to validate the flag methods on Move
I caught a bunch of bugs while implementing position::MoveBuilder in the flag
methods that Move exports. These tests caught many of them!

f90ea2d1be [board] Add a test for capturing en passant; fix the bugs
I wrote a test for capturing en passant that revealed some bugs. Cool!

Implement the missing part of move validation that checks for an en passant move.
Implement PositionBuilder::to_move() to set player_to_move.

The most difficult part of this fix was finding the logic error in
Move::is_en_passant(). Instead of checking for non-zero, check for equality against
the en passant flag value. Checking for non-zero was causing this method to return
true in the double push case.

21b5266789 [board] Implement position::builders::MoveBuilder
This builder takes a Position and a Move, validates the move, and makes the move
in that position. Its build() method returns a new Position with the move made.

This a neat trick!

24cce95a88 [board] Implement a PositionBuilder; refactor piece bitboards into a PieceBitBoards struct
This makes Position immutable, even if declared mut. I think this will also make
it easier to build positions going forward.

Moving to a PieceBitBoards struct also required a lot of places that return owned
BitBoards to return refs. This is basically fine except for adding a few more &
here and there.

This was a huge refactoring project. All the move generators and a bunch of
BitBoard stuff needed to be updated.
