no help but annoyingly i misread the hint about low/high and didn't submit my *correct* answer for over an hour while I bug hunted!

not proud of this one either, completely cheated and it does not get
exactly the correct error (it was off by one for my input), but the
quadratic solver on Wolfram Alpha was able to do it.

another unsatisfying one where i needed a visual hint to grok what i
should be doing.
a bunch of graph building stuff that wasn't needed for the part 1
solution at all.

day16: back to elegant recursion now that we track beams
...
problem 1 solution was busting the stack, so used an iterative approach,
but now that we track lit beams we can bail out early enough not to bust
the stack. performance is the same but it's much nicer.

what a doozy. iterative solution from part 1 totally untenable.
recursive solution a bit tricky, but still not fast enough for brute
force. had to implement memoization cache for reasonable runtime.
