[position] Refactor sight routines
...
- Break out the actual routines into file-private helper functions
- Declare traits for each piece type that call the corresponding helper function
- Implement these traits on PlacedPiece
The sight routines changed slightly such that they include the player's own pieces
in the resulting BitBoard. The tests neeeded to be updated to account for this.

Well… all the tests except the Peter Ellis Jones tests.
Pass around whole EnPassant types instead of pulling out just the e.p. square.
Make sure that Castling moves have their target and origin squares populated.
Add a color field to the Castle move style to make this possible.
