day 24 finish in m4
Part 2 in isolation (use m4 -Dskip1) takes only 370ms, quite a bit
faster than part 1! Go ahead and copy my Gaussian elimination out of
LibreOffice and implement it directly in m4 instead. Since I'm
guaranteed integer results, I only do seven divisions at points where
I know there will be no fractional result.
