Enable anonymizing images uploaded to Open Products Facts

Problem

• Some OPF products have serial numbers (and even IMEIs)
• Enable anonymizing images uploaded to Open Products Facts
• example: https://images.openproductsfacts.org/images/products/400/251/646/5621/4.jpg

Similar to prices proof, then?

Yes, reusing the same mechanism 👍

For prices proof, there's one upload and that's it. Section removals are applied to the image before it's uploaded.

For off images, we either add new images or crop existing images.
Looks like for new images we can add the same mechanism as prices proof: being able to strike out sections of the image, with no turning back (e.g. no way to remove removals).
For existing images being cropped, it'd be fair to assume that the anonymization was already performed in the root image, and that we don't need the anonymization tool.

Yes, new images is all we care about.
