Filtering for copyleft schemas #3428

[zbirenbaum]

Here's a clean branch we can work off of to replace #3428

I applied the change from list to List for backwards compatibility as well

As I mentioned I think there's a bit more to do here. The setup process breaks due to pyyaml not being available.

I fought for a while and got it working for installing through pip from git by adding the pyproject.toml file but I couldn't get the publication process for pypi to run properly when we went to publish a temporary version for our sdk release.

Fixes: #3427

• List of Copyleft licenses
• Detection/filter to the compilation script
• Regenerates the manifest
