Support for multiple base paths

[usox]

Hi

I have several server specifications in my openapi definition. These differ primarily in the base path (e.g., the API has a different base path in the dev environment than in production).
It would therefore be good if the different servers were taken into account when looking up the path.

If I find the time and the feature is desired, I can extend the path finding (and whatever else would be affected) myself.

@usox Hi! Thanks for the feedback! Yes, the feature is definitely necessary, and I planned to implement it much later, since the priority now is on stabilization and bug hunting. I think I'll make such a feature after I refactor it. Therefore, if not urgently, then I will do it by version 0.5.0 (I think it's worth making a roadmap in the readme)
