Use CDN instead of including the library files

Is your feature request related to a problem? Please describe. No.

Describe the solution you'd like At the moment the shortcode requires the user to include the library files locally. This will be a maintenance problem as the library will have to be updated everytime there is a new release.

Describe alternatives you've considered Ideally the library can be included using a CDN. If not available then consider other projects / libraries that include PDF.js and provide a CDN.
