feat: Add huggingface.LocalHFDataset to kedro-datasets

[iwhalen]

Description

Adds LocalHFDataset for interacting with datasets.Dataset on a filesystem instead of the remote Hugging Face hub.

This has been a big missing feature for me when using huggingface.HFDataset. We can pull things from the hub, but not save them off to a local file / directory.

Development notes

Added docs, tests, ran in a fresh pipeline.

Iterable and in-memory versions have both been tested as well.

Note

I couldn't figure out a good way to save an IterableDataset without looping through it entirely first.

Maybe there's a better way someone knows about.

Updated jsonschema/kedro-catalog.1.00.json.
