Add support for using `huggingface_hub.HfFileSystem` as a remote

[petebachant]

Assuming this would be fairly straightforward since it's already an fsspec compatible class. What all would be required? I'm happy to work on it. My guess is that there needs to be a new plugin dvc-hf, and an update to dvc-objects to add the scheme.

DVC supports git-lfs, so it can import/download files from huggingface repositories. See https://dvc.org/doc/user-guide/integrations/huggingface.

This is a duplicate of #9327.

Could you elaborate on the feature request? Specifically, what does a Huggingface remote would offer and how it would simplify the workflow for you?

Also, why use DVC in that scenario? Since you can import directly from Huggingface and use it in pipelines, is this primarily about convenience?

This would be using HF as a full-featured DVC remote, so, for example, dvc push will send objects there. I assume they will be saved with their md5 as the file name, but that's okay. It's simply meant to be a storage location, and HF offers generous free storage limits.
