Fix deprecated huggingface download

[timholds]

In case it helps anyone else, I fixed an error downloading the model from Hugginface! In your example.ipynb there is a warning about the same.

/home/user/conda/lib/python3.7/site-packages/huggingface_hub/file_download.py:654: FutureWarning: 'cached_download' is the legacy way to download files from the HF hub, please consider upgrading to 'hf_hub_download'
  FutureWarning,

The change replaces the two-step process (generate URL, then download) with the direct hf_hub_download function which takes the repo_id and filename parameters. It also updates the paths[model_name] value to use the actual path returned by hf_hub_download, which I suspect will be more robust if the HF cache structure changes.

By the way, cool repo and thank you for sharing it!
