Updated embed method from iframe to JS

Libraryh3lp has a never pure javascript recommended way of implementing their code, which as I gather allows the admins of the system to route the widget to the correct queue.

We've already done this on library.nyu.edu:

@etgrieco I keep forgetting about this. Could you make this update in this module and deploy it across NYU/NYUAD/NYUSH/NYSID?

Noting that NYSID uses different queue/id/view vars

Thanks!

Yes! Definitely will get this done -- something I can jump in-and-out of today
