Add support for amenity/library in operator tree

[arch0345]

This is similar to other categories I've added to the index in the past: amenity/school and leisure/park.

There are many public operators of libraries that operate multiple locations (at least in the US), so adding this category in the index could be beneficial. So far the only entry I've completed is the New York Public Library, but it looks like a lot more have been collected from the latest planet file.

Agreed, Wikidata even imported a database of over 17,000 U.S. library systems and branch locations, so there’s a lot of room for this tree to expand (and for individual branches to be tagged). Alas, it’s probably too late for @bhousel to spin up another massive Hacktoberfest issue series around these library systems.

I agree with this amendment, because many times libraries appear in groups, especially when the government or some charitable organizations form groups to improve cultural and educational conditions.

Good idea! 👍

Yes I think it's too late to promote it widely, but not too late to send in 4 PRs and earn some swag 👕 or plant a tree 🌱
