Add isInTaxonomy boolean flag in ingredient parsing result

[alexfauquette]

Problem

The API does not provide a clean way to know if an ingredient is already in the taxonomy or not.

We can guess from the fact that an ingredient get a ciqual_proxy_food_code or vegetarian attribute that it's in the taxonomy, but there is no way to know when an ingredient is not in the taxonomy.

Proposed solution

Adding isInTaxonomy for all ingredients at the same time the server is looking for ciqual_proxy_food_code

Additional context

Would be useful for hunger game ingredients. And I think robotoff also needs it and for now is using a workaround

No idea where it is

I'm interested in this issue and would like to resolve this.

Related code is in lib/ProductOpener/Ingredients.pm
in the parse_ingredients_text_service() function (it's a huge one).

At the end we should add a boolean field "is_in_taxonomy", using the exists_taxonomy_tag function, near this code:

			if (not $skip_ingredient) {

				my %ingredient = (
					id => get_taxonomyid($ingredients_lc, $ingredient_id),
					text => $ingredient
				);

Note that a lot of tests will need to be updated after that, so you will need to run "make update_tests_results", and possibly change manually some tests results in *.t files

Note that Perl doesn't have Boolean type, so instead we should return 1 for true, and 0 for false.

I'm understanding the function refered to. Thank you for the references
