Setup a CI

[MaikKlein]

We need a ci that builds and tests

• [x] All of the rust crates in this repo

We need an CI for unreal.

• Cross compile on Windows and Linux
• Lints: clang-tidy, clang format, and more
• Package examples for Windows and Linux

Github actions: Actions doesn't seem to be capable of running the docker images for unreal. Neither the standard nor the slim image seem to work and both run out of diskspace.

Maybe we can set up our own server for this? I'd be happy for some advice here.

@MaikKlein I'm far from a CI expert but from a little googling I think the easiest solution would be using a larger GitHub-hosted runner. The only downside is that you need GitHub Team ($44/year) but I don't think you're going to be able to run something as big as Unreal for free anywhere without hosting your own server.

Thanks I didn't know that there were large runners for github. I'll give it a shot. I was also looking into other solutions like https://circleci.com/blog/optimize-unreal-engine-builds/ but that's definitely a bit of a hassle.
