Implement logos & labels crops fetch and annotate routes

[teolemon]

Why - Problem description

• We are now able to predict labels 300ms after image upload
• Sometimes it's applied automatically, sometimes we have a prediction that needs to be validated
• We'd like to let the user validate that in edit mode or product addition mode, beyond the classic Yes/No Robotoff questions
• The route allows to filter on a given barcode, and get all crops for it

What - Proposed solution

• Implement logos & labels crops fetch and annotate routes

Alternatives you've considered

• Have an abstract Robotoff API (poke @raphael0202 )

Additional context

• Documentation: https://openfoodfacts.github.io/robotoff/references/api/#tag/Logos

For the moment, if you go to https://robotoff.openfoodfacts.org/api/v1/images/logos/search?barcode=3560071232719&annotated=true, you get answers like

"annotation_value": "en:nutriscore-grade-b",
"annotation_value_tag": "en:nutriscore-grade-b",
"taxonomy_value": "en:nutriscore-grade-b",

@teolemon @raphael0202 Does that mean that we need an additional call to the taxonomy API in order to get the localized name instead of the tag?

For the moment yes, we do..

Sometimes it's applied automatically, sometimes we have a prediction that needs to be validated

For information insights derived from logos KNN are never applied automatically! Only when the logo was manually annotated.
