Feature request : Add support for lazy loading images

[TheCapsLock]

To make our pages load faster and minimize the use of bandwidth/memory when a user does not scroll a whole page ; we can use the following attribute to make the image load only when needed (lazy loading):

<img src="image.jpg" loading="lazy" />

This can be done using a shortcode, I'm not sure how else it could be done. Maybe a setting in the config.toml.

Oh that's nice, I didn't know that attribute. Right now you can do it with a shortcode.
Adding it to the parser is more involved as it's unlikely to be added to pulldown-cmark as they don't seem to add more features. Maybe it could be added to Zola.
