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.

day6: further performance improvement, ~55ms total runtime
...
We only need to run the guard forward from the step before the obstacle
we placed, instead of starting at the original starting position.
The code starts to look ugly...

* I misunderstood the problem and thought we were asked for the distance
between the numbers' positions, not their values. Removed remnants of
that.
* Move to struct-oriented solution
