Package shading draft

[mhutch]

Ready for review!

~~FYI the diagrams don't show up correctly in the GitHub PR "files changed" but you can see them if you view the document in the branch.~~ (edit: GitHub now supports Mermaid natively so I converted the diagrams to use that, but earlier commits still have PNGs with embedded source)

Sorry for necroposting. Is anyone still working on this?

@foxyseta here is my effort at an implementation https://github.com/getsentry/dotnet-assembly-alias

Thank you! This definitely sounds like a good tool to use while waiting for shading (or similar functionalities) to be natively integrated into NuGet. Hopefully, I'll have time to take a deeper look into it and drop by.
