Suggested change to get_image function

I made changes to the plugin on one of my sites, and suggest this change for the plugin itself.

in file: classes/functions.php around line 430 this code is present:

            $class = $class ? ' class="'.$class.'" ' : '';
            return '<img loading="lazy" '.$class.$alt.' src="'.wp_get_attachment_image_url( $attach_id, $size ).'" />';

My change is the following:

            $class = $class ? ' class="'.$class.'" ' : '';
            $srcset = wp_get_attachment_image_srcset( $attach_id );
            return '<img srcset="'.esc_attr( $srcset ).' loading="lazy" '.$class.$alt.' src="'.wp_get_attachment_image_url( $attach_id, $size ).'" />';

What this does is adding srcset to the images, making a PageSpeed score higher and loadtimes faster.
