Add support for Photo Sphere (360°) panoramas

[DecaTec]

Describe the feature you'd like I often create 360° panoramas. When uploading these to MediaCMS, these are not shown as Photo Sphere Panoramas, but as "flat" images.

You probably know Photo Sphere from Google (maps), these are 360° panoramas, you can take a look at an example here.

Additional context There are a few libraries out there, e.g. Photo Sphere Viewer (or GitHub). Maybe these could be integrated into MediaCMS.
