Dupe of https://github.com/dotnet/machinelearning/issues/5649.

Support for multiple group by wasn't high priority when GroupBy was implemented, but I will make a run at this after .NET 6 work winds down and there's more time.

I made it on my own codebase (not in github) - I think I can provide the same functionality in this repository
