scripts : add --outdir option to hf.sh (#6600)

* scripts : add --outdir option to hf.sh

This commit adds an option to the hf.sh script that allows the user to
specify an output directory for the downloaded file.

The motivation for this changes is that examples that use the hf.sh
script to download models from huggingface can now specify the output
directory, perhaps to the `models` directory to keep them in one place
and not clutter the root directory.
