Advent of Code: Go library stuff

These are basic tools and functions for the actual Advent Of Code solutions.

Disclaimer

These are my personal solutions of the Advent Of Code (AOC). The code is not indented to be perfect in any kind of area.

If you think, there is a piece of improvement: Go to the code, fill a PR and we are all happy. Share the knowledge.
