Level up the license detection for nuget packages

[sensslen]

We're currently looking into adopting the SBOM tool for our projects. However we heavily rely on nuget to provide external dependencies. While the SBOM tool already provides very basic support for .net it does not provide nearly complete information.

I do maintain a .net tool that provides much more comprehensive information for nuget dependencies in particular. Would it be possible to collaborate to integrate nuget-license into the SBOM tool as a plugin for example?
