create_baseline_stubs.py script does not add default values

As title says. Now that typeshed prefers having default values, it would make sense if the create_baseline_stubs.py script added them.
Maybe that would be stubgen's job?
For now I'm running https://github.com/JelleZijlstra/stubdefaulter manually as I am moving stubs out of https://github.com/microsoft/python-type-stubs, but I don't think that's even documented/mentioned in the contributing guidelines.

Yeah, really this should be added to stubgen, but in the meantime, I wouldn't be opposed to adding a stubdefaulter step to create_baseline_stubs.py

Given that stubdefaulter is only avaiable from github, it won't be cached by pip. Meaning if I add it to requirements-tests.txt, it'll cause extra unnecessary downloads for the CI.
Do you think it's a better idea to catch it as part of the create stub script? If not installed, stop the script and tell the user to install stubdefaulter? (python -m pip install git+https://github.com/JelleZijlstra/stubdefaulter.git#egg=stubdefaulter). It would be added to the initial pip install doc too.

Or ask @JelleZijlstra to publish the tool on PyPI. But if usage in create_baseline_stubs.py is meant to be "temporary" (you know how these things go sometimes :P ) until added to stubgen idk if worth it.

Thoughts?

Oops, I missed the description. I guess that's for 0.2.0 :)

Awesome.
