Add feature to clean /bin /obj folders with restore NuGet packages

[imuller]

When removing the /bin /obj folders i always need to restore my NuGet packages, else i cant build the project. If there is a option to clean the folders and also restore packages, the process would be a lot faster :)

This is because when using PackageReference, generated files for NuGet packages live somewhere in the obj folder for each project.

But yeah, there could be an option to nuke + restore.

Sounds reasonable. Change the status to help wanted.
