Developer filter to generate thumbnails via CloudFlare Image CDN

[Alejandro]

Hi

This came out of recent collaboration with a client. Keep in mind that right now this only works on Business and Enterprise plans.

You can find other dev filters and code snippets here https://gist.github.com/jreviews

Enjoy!
