Allow deleting a subset/config from a no-script dataset
As proposed by @BramVanroy, it would be neat to have this functionality through the API.
Probably best to implement this as a CLI command? Thanks for your comment, @mariosasko. Or maybe both (in Python and as CLI command)? The Python command would be just the reverse of `push_to_hub`...

I am working on a draft implementation, so we can discuss about the API and UX.
