Advent of Code 2022

Also my attempt to practise writing some idiomatic Go.

Goals

1. Be as idiomatic as possible
2. Ensure decent test coverage with unit tests
3. Automate as much as possible, from input parsing to test suite running

Non-goals

1. Solve problems as fast as possible (I'd LeetCode for that instead)
2. Unnecessary performance optimizations
