Check code compatibility including dependencies

[ego-lay-atman-bay]

I just recently used vermin to check what the minimum python version my module can run on, and I got 3.8. I set up a 3.8 venv to verify that it could indeed run, and then when I installed the dependencies (requirements), it through an error saying that numpy didn't have a compatible version.

I'm wondering how I can use vermin to check the minimum version my code can run in, as well as external modules.
