relative imports test demo

[vors]

Hello!

This is a quick repro for existing problem with relative imports: they are treated like non-relative imports at the moment, but ideally they should take into account the passed filename.

I think it's a limitation of used python parser library from what i can tell.

Thanks for the PR. Have you looked into how we are parsing the python here. It would be nice to support this construct.
