Branch issue-103 created!

[ElBe-Plaq]

An error crate is still needed probably, so the errors won't have to be created manually everywhere. This crate could also become part of tools.

I can't really find a good starting point for the errors, it'll use thiserror and anyhow. I think someone else might want to do it. (Please) @Ranastra ?

[ElBe-Plaq]

@Ranastra said no, I'll have to do it.

[ElBe-Plaq]

I'd really want to add ? and Result<...> everywhere and I'll do eventually, but at the moment I'm fine with this.
