NitroImg v1.4.1 - Responsive WebP in Page Content

Content images served as WebP now get a responsive srcset instead of always loading the full-size crop.

Responsive images

• Srcset rebuilt for WebP content images - WordPress could not build a srcset for an image whose src is WebP, because the WebP filename never matches the size files recorded in the attachment metadata. Every such image rendered with no srcset at all.
• Smaller crops finally used - the crops NitroImg already generated were being created and never served. Phones now download a phone-sized image rather than the full-size one.
• Converted images only - images NitroImg did not convert keep their original src and WordPress builds their srcset natively, unchanged.
