Advent of Code 2020 - Day 20

I'm continuing to stream Advent of Code 2020! Here's day 20. Today was quite rough - I missed the "easy" part 1 solution (despite checking for it!) and did it the (very) hard way instead - 1119/106. I made up for some lost time with more magic regexes, but it wasn't enough to get me on the leaderboard today.

This took me the whole day to solve xD

nice!, these intermediate prints slows it down very much
once you not need them, comment them out
and with pypy it should run ~1sec ;-)

and one comment, could you please increase font size, at least in editor, I'm hardly seeing something there..
