Subject: [PATCH] Add custom elements on content output

By using `the_content` filter instead of `content_save_pre`, the custom element `<pwp-lazy-image>` is added on the fly before the content output. This approach avoid to get stuck to PWP Lazy Image plugin in the future: you will be able to switch between themes, lazy load plugins, or even between publishing platforms without the need to rewrite every post.
