day10: optimization
...
Part 2 doesn't actually require tracking state at all, it's enough to
just follow the rules and count every DFS that lands on a target square.
Part 1 optimized by only tracking which targets have been previously
visited, instead of all squares.
Both parts, pass position reference to recursive calls instead of by
value for tiny improvement.

We only need to run the guard forward from the step before the obstacle
we placed, instead of starting at the original starting position.
