Might help with #473
(Got another feedback today that the current scanner doesn't work all the time)

Looking at the current list, I'm not sure other components are very useful for the prices project.

However, I'm keeping an eye on the search-a-licious one. It's currently being integrated to openfoodfacts-explorer (see openfoodfacts/openfoodfacts-explorer#180), so we'll let them do the heavy lifting and copy the final solution :D

@TTalex @raphodn potentially Nutripatrol for reporting, and the folksonomy engine to report weird stuff.
You can also consider robotoff questions to improve experience on incomplete products
