Being able to download products that present opportunities for improvement

[manon-corneille]

It's been requested by many producers to be able to download data of products that present opportunities for improvement.

• From this page: https://world.pro.openfoodfacts.org/possible-improvements
• but also from the specific improvement page:
  ** https://world.pro.openfoodfacts.org/possible-improvement/nutrition-high-salt-value-for-category
  ** https://world.pro.openfoodfacts.org/possible-improvement/better-nutri-score-with-much-less-salt
  etc

What to export?
Barcode, Name of the product, Score name (e.g. Nutri-Score), Current score, New score, Nutrient to change (e.g. salt), Current value, New value

This will give actors the opportunity to bypass the Pro Platform (eg consulting firms acting on behalf of clients). We're not good at gauging reformulation impact, and that will worsen it a bit more.
We should track downloads, and then ensure we pester downloaders for impact metrics.
