Allow 'text/javascript; charset=UTF-8' as JSON valid format

I'm trying to embed a facebook link using the library and I'm not able because FB oEmbed response is in formar 'text/javascript; charset=UTF-8' instead of 'application/json'
https://developers.facebook.com/docs/plugins/oembed-endpoints
Would be great if you could add this to allow to embed FB posts.

Thanks
