Feature request: Support for WebP images via <picture> tag

[Jarzka]

(I know you asked us to post feature requests to Stack Overflow, but SO is more for questions than feature requests so I post it here)

It would be awesome to save bandwith and use picture tag inside the lightbox2 modal dialog to load images in WebP format, while providing JPEG fallback at the same time.

This is a great idea and something I've put into the v3 brainstorming roadmap: https://github.com/lokesh/lightbox2/blob/dev/ROADMAP.md
