Importlib invalidate caches

Sometimes when you install a Python module while running Python, it won’t be importable until a session restart.

To fix this, if any modules are created/installed while your program is running,
run importlib.invalidate_caches() to guarantee all finders will notice the new module’s existence (and be able to import it).

This does not reload any modules already imported, so old code might still be running.
