CarolinePascal 3ea347a3d9 migration: add extract_dataset.py to pull a sub-dataset into a standalone repo
download_subfolder gains a repo= arg so it can source from any monorepo; the new
extract_dataset.py scoped-downloads one sub-dataset and re-uploads it at the root
of a new standalone dataset repo.

"""Extract one sub-dataset from a LeRobotDataset monorepo into a standalone HF dataset repo.
Downloads only ``{src-repo}/{folder}/...`` (scoped listing, no whole-repo walk) and re-uploads
its contents at the ROOT of a NEW dataset repo, so the result is a self-contained LeRobotDataset.
python extract_dataset.py --folder wannrrr/etnai --dst-repo CarolinePascal/etnai
