We filter out already visited states when adding them to the work list.
We also don't sort the work list as we're already generating it in a
sorted (by cost) order.

Performant solution to 2024 day 11.

We notice that we're repeating calculations at each step, so use a
map to ensure we do each stone ID once per step.

Not happy that mutable state is being used. But this seems to be the
simplest way, and is efficient.

Simplify the code for 2024 day 7
...
Simplify may be in the eye of the beholder here.
This reduces code duplication, as both parts are effectively the same.
Part 2 just has an extra operation that can be carried out.

Do not use a set to record blocks in 2406.ml
...
Instead of using a set of locations to store the blocks in day2406.ml
return to using a string.
Sets have an O(lg n) lookup time in number of blocks.
Instead we use a single string which contains the whole map, which means
we can do O(1) lookup on a block. This significantly improves
performance.

Move IntPair and PosSet into Aoc library.

These are obviously generic enough and useful for the future that they
can be moved to a shared library.
