day 17: sort containers descending
day 17: sort containers descending

Intuitively it makes sense to look at the bigger containers first
because they are more likely to cause other containers to be unusable.
Looks like this sped me up 0.25 -> 0.20 seconds. Small but I think it's
consistent. Sorting ascending gave 0.40 seconds or thereabouts.
