Implement open food facts API about grocy-android

Also calories could be used when the calories field is implemented in the product edit page.

Hello,
Great enhancement 👋😊

From the Open Food Facts API Documentation

READ requests allow you to retrieve the nutritional data of a product with a barcode.

GET https://[countrycode].openfoodfacts.org/api/v0/product/[barcode].json

Example:
GET https://world.openfoodfacts.org/api/v0/product/737628064502.json

Authentication
No authentication is required for READ operations.
However, you have to add a User-Agent HTTP Header with the name of your app, the version, system and a url (if any), not to be blocked by mistake.

Example: User-Agent: NameOfYourApp - Android - Version 1.0 - www.yourappwebsite.com

Json format to get product name:

https://world.openfoodfacts.org/api/v0/product/42100454.json

User-Agent: Grocy Android - v1.2.0 - https://github.com/patzly/grocy-android

{
    "product":{
        "product_name":"Alnatura Mandelschnitte, Mandel"
    }
}

We'll leave it at the product name for now.

@patzly Probably is it possible to add also:
https://github.com/openfoodfacts/openbeautyfacts and
https://www.codecheck.info/
?

https://www.codecheck.info/ is not possible because the API is not open – and it is also protected via Google Captcha.
But maybe we can implement https://world.openbeautyfacts.org/, I will open a new issue for that.
