day 10 optimize
From the megathread: I basically implemented ray-tracing parity from
scratch, except I did it complicated by tracing through the middle of
the pipe. Instead, trace just through the top half of a cell at |JL,
and there is less work to do (only the north neighbor matters). Now
~175ms.
