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?
