Regenerate the Top 10 plastics JSON data file

The Top !0 plastic types by country data from the combined dataset includes plastic types not used in the game (usually "other" plastics or combined plastic types, like foam/plastic plates. Need to create a Top 10 plastics file for the countries in the game that only contains plastic types used in the game. It will need to be generated from the plastics by country files with logic to only include relevant plastic types.
