Finish Huggingface feature

[pcolange]

The Huggingface model ingest feature is available but hidden by default and is considered to be in a beta state. The reason is that the UX isn't quite there and there are a few race conditions that can occur when clicking open ONNX model for multiple files before the previous is finished downloading. The features we need to implement to close this issue:

• Prompt the download process. This will require grabbing (inheriting) the HF tqdm progress.
• Once we have the prompt we should use it to force only a single download at a time
• If not done already we should process all the Huggingface tasks on a separate thread
