Implement JavaScript library dependency and document asset packagist installation

Currently not possible, as the library currently does not have a proper bulilt js file, when we get the library through https://asset-packagist.org/package/npm-asset/js-cloudimage-360-view.

Here's the related GitHub issue: https://github.com/scaleflex/js-cloudimage-360-view/issues/122

I'll assign this to Scaleflex for that reason. Please ping here once it's fixed so we can add the composer integration maybe.
