CDN updates

{cdn} {image processing}

Previously, when -/format/ was not specified, we attempted to preserve the original image format (e.g., providing PNG if the original was PNG). Now, we choose a format based on the content. If the image appears to be an illustration, PNG will be used. Please note that you still need to explicitly specify -/format/auto/ for AVIF and WebP output.
New option -/format/preserve/ is added.
