Feature request: lua-callable function to return all plots of a specific trade route

[Tekamthi]

I have a few mods that apply special rules to trade route plots. It's not very efficient however: afaik (memory is a little foggy on the details) mod checks all plots at start and builds table for all players tr plots. From there it rechecks all plots each time a tr starts or ends using Lua hooks, and rebuilds that players table. There is no way of which I am aware to return just the plots affected of the new/ending TR -- we can be notified of some of the details but not the plots

So request is to have some kind of function that returns an array of plots when given a tr identifier.
