Advent of Code 2021

It's that time of year again. Featuring:

• Python 3.10 - let's do some pattern matching!
• Golang 1.16 - cause that's what's in Fedora 35's repos. And it's awesome.

Python conventions

• Code formatted with black (with one exception: line length == 120 because 21:9 gaming monitor).
• 10/10 Pylint with as few exceptions as possible.
• Only Python code goes in the aoc2021 folder. All puzzle input is saved in fixtures.
• Everything should be runnable as a module from within the python folder - e.g. python -m aoc2021.day1
• Remember that your input is not necessarily going to match mine. That being said, tests will contain spoilers. Tread carefully.
