Add API to get details of ancestors of a node

Something like this probably exists already in order to populate the "where am I" popup bar, but I have reimplemented something for Chris Haughton and Tiziana

This happens entirely in the client, as it already has the details to hand: https://github.com/OneZoom/OZtree/blob/bfcc84f67a3ea3ba7864d345486483606468e798/OZprivate/rawJS/OZTreeModule/src/controller/controller_loc.js

We also have the highly-related common_ancestor_of_otts:

Remove the filters at the end of the query and it'll return the full path to the root.
