Request webp file support

Hi. Have been using your Pro version plugin for a long time and love it. It didn’t seem webp files worked, but after adding that extension in the plugin front end code, it seems to work at the page I linked. Could you please add .webp files permanently? I’d like to start using webp images on my site and would like to keep using your plugin. Thanks for considering.
