Rebase to 7.0.0

Let's get this merged into:

Tests require protobuf latest (not available in Python 3.7) to pass, two solutions:

1. Rebuild with old protoc 3.x with the recommended ~4.23 in OG setup.py
2. Make the case for protobuf version upgrade (Time for a Protoc Upgrade? Vlsir/Vlsir#105)

So, in Vlsir#105 we've decided to go with option 2. I just need to implement a fix for Python 3.7, then I'll get Cline to crawl and autodoc and then compare this against reality.

Could we just stop supporting 3.7?
Maybe add 3.13 eventually since it is now stable?

Both 3.7 and 3.8 are end of life:

Good point. Raised in Vlsir#106.
