Add example with std library module

[mohammed-ali-1]

This PR adds a slightly more complex fourth example file that shows how a target file can also import a module from the Python standard library.

While working on the PR I encountered the following 2 issues:

1. vulnerable dependencies which were updated in bc7da59
2. mypy issue with __ror__ overload of dict which was fixed in cc6e052

Finally, I bump up the version in ccb4234 to 0.2.0.

I'd appreciate a quick lock just to make sure I didn't miss anything.

LGTM, thank you!
