Advent of Code 2023

This year, after much debate I will be using golang for the annual advent of code competition.

While this is a repeat of 2020, golang and it's ecosystem seems to have moved on quite a bit since then.

Of the features I know about, generics is the one that I expect will be the most useful.

While I have in previous years created test cases, this year I've been challenged to stick to a more tdd-focused approach (rather than simply test to execute).
