Localization support

[NebelNidas]

Inspired by Enigma's and JADX's equivalents, but heavily stripped down. Only supports mapping format names for now, exception messages are going to be tackled in a separate PR.

I dont think we should localise error messages like this
It makes it harder to search for solutions, harder for people trying to provide support, and doesn't really benefit users. We dont localise error messages in other projects, especially none user facing ones like this.

We could maybe introduce error codes that make it accessible for replacement on the embedding application side?

That's the goal, having a central ErrorMessages class holding all the error messages MIO uses in the form of Translatables. Consumers can either translate the Translatable to a given locale, or manually check for equality with a given error message.

But as mentioned above, that's going to be a separate PR (probably after #94 is merged)
