Publish personal search product ranking code as separate external JS library

[stephanegigandet]

The scoring and ranking of search products according to user preferences is currently done in 2 functions in https://github.com/openfoodfacts/openfoodfacts-server/blob/master/html/js/product-search.js

In order to make it easier for other apps and sites (e.g. the OFF browser extensions) to personalize search ranking, we could publish those 2 functions in a separate JS library that we could then publish on NPM.
