Automatic openapi generation

[SorenHolstHansen]

As pavex is a compiler, it would be cool to explore the possibilities of generating openapi specs for the blueprint.

I understand that this might not be that high on the list of features at the moment, but I think it is one of the biggest pain points when creating APIs, and I would love to see pavex's take on it.

This is definitely on the roadmap 😄 Once the work on the core stabilises, it'll be one of the first items I'll start working on.

That sounds amazing!
