Function makeMove

makeMove(board: BitboardState, move: BitboardMove): BitboardUndo
Plays a move, mutating the position, and returns what unmakeMove needs to take it back. Special moves are read off the position rather than flagged on the move: a pawn onto the en passant square captures the pawn behind it, a king stepping two squares swings its rook, a pawn stride of sixteen leaves a square behind it.
Parameters
- board: BitboardState
- move: BitboardMove
Returns BitboardUndo
Example
```
import { bitboardMoves, makeMove, startingBitboard, unmakeMove } from '@datamoc/mwg/board';

const board = startingBitboard();
const move = bitboardMoves(board)[0];
const undo = makeMove(board, move);
console.log(board.turn); // 'black' - the move is played
unmakeMove(board, move, undo);
```
