Allow deleting a subset/config from a no-script dataset
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. 2nd time I've come here in the past few days so for reference this doesn't work for me at the moment (token auth error despite successful `whoami` and all auths applied) so I resorted to [reverting](https://discuss.huggingface.co/t/how-to-revert-to-an-earlier-commit-on-a-repo/65735/2) to a previous commit (after installing git lfs)

```
# git lfs install
GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/datasets/USER/REPO
cd REPO
git reset --hard HASH
git push --force
```
As proposed by @BramVanroy, it would be neat to have this functionality through the API.
