WebP Me for Craft CMS

Simple function that returns a WebP formatted image url if the visitors browser and the server supports WebP, if not then it will fallback to a standard image url.

If both the server and visitors browser supports WebP, the passed image will be converted to WebP unless the passed image is a SVG.
If the visitors browser does not support WebP then the image will not be converted and will maintain its current format.
If the passed image is already a WebP image but the visitors browser does not support WebP then the image will be converted to a PNG (incase of transparency).
