(feat): resolving asv env explicitly

Fixes #31

So obviously this python string business is not ideal but I am not sure what else to do. The python file doesn't copy over with the build after compilation so as far as I can tell we can do it manually or it's PyO3.

Nice! Just some nitpicks, assuming you want them: There’s two possible ways to make the Python script nicer, and the tests can be a bit more concise.

For further unit tests in this vein, I wonder if we should look into mocking. But that’s for another day.

Thanks so much for my first rust review @flying-sheep 😄

I briefly looked into it, but it seemed like too much of a rabbit hole for right now, agreed.

I unified the tests a little, looks great!
