Leverage the Webpacker gem to incorporate Mirador Viewer into GeoBlacklight

Mirador is an open-source, web-based, multi-window image viewing platform with the ability to zoom, display, compare and annotate images. It was built on the ReactJS framework. It is fully compatible with International Image Interoperability Framework(IIIF) specifications.

Webpack is a tool that lets you compile JavaScript modules. Given a large number of files, it generates a single file(or a few files), helps you manage the increasingly complicate dependency graph.
