more formats, memoizing, custom <picture> element generation, async image conversion to optimise CPU usage, and more! Too bad that the imagemagick apt package doesn't natively support JPEG XL just yet (Imagemagick 7 does though), but that's an easy fix on our end once they add support :D It looks like we need to implement our own alternative to the serve command though :-/
