Add Gradio Support

[julien-blanchon]

Gradio App is an open source machine learning interface running on top of Python : https://gradio.app/

It's quite easy to implement and very hackable.
It's also compatible with Hugging Face Space (https://huggingface.co, https://huggingface.co/spaces).

I may help user and researcher to:

• Quickly debug their model (infer without any line of code, provide web drawing tool ...)
• Showcase their work
• Share model with the community (ie Hugging Face Space ...)
• Flagging unexpected behavior

I've implemented a quick example with my EuroSat Dataset here: https://github.com/julien-blanchon/anomalib/tree/gradio
It may for now only work with segmentation

Great stuff! It was on our todo list.

@julien-blanchon, brilliant! As @ashwinvaidya17, it's been on our list for ages, just didn't have time to implement it

[julien-blanchon]

I don't have the right to create a new branch here, I don't feel comfortable enough to request a merge with current project branch https://github.com/julien-blanchon/anomalib/tree/gradio

@julien-blanchon feel free to create a PR from your fork. We squash commits before merging in case that's what you are concerned about. We can always polish the rest in the PR review.
