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.
