5094e92d31 Tidy up code for 2024 day 9
Not happy that mutable state is being used.  But this seems to be the
simplest way, and is efficient.

54f14c0492 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.

799a25464b 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.

831bbf4f63 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.

38d0781c7e Reimplement 2024 day 6 to use a set.
This seems "better" from a functional perspective.  However, it runs
substantially slower for part 2.
