support for next-gen webp, avif image conversion on upload and insert

[QuintinHumphreys]

i have some large scale commerce websites in production using DNN, my latest one is on 9.11.1

i have noticed more and more clients require next-gen image formats for SEO/speed purposes however i cant seem to find any plugins or core support for this.

wordpress has some neat plugins, however no core support.

it would be an achievement for DNN to beat Wordpress on something like this that seems so simple.

stage 1
a simple "convert to Webp" button in the image uploader (also in file manager) which keeps a copy of both, webp image option inserts images as with jpg fallback

stage 2
html editor config option to default all images to web-optimised images where it scans all content in the document, finds remote or local images, copies the image locally, converts to web optimised or jpg (a copy of both), recreates the image tag as picture tag with fallback from web optimised to jpg version
