IAP: Preserve triple hyphens while generating image attributes.

/**
 * Preserve triple hyphens while generating image attributes.
 * 
 * Replace triple hyphens in image (---) with a placeholder (IAPHYPHEN) in the image filename.
 * Image Attributes Pro already replaces IAPHYPHEN back to a single hyphen ( - ) after applying filters 
 * in iaffpro_image_name_from_filename().
 * 
 * @param $image_name (string) Name of the image.
 * @return $image_name (string) Name of the image with triple hyphens replaced by IAPHYPHEN
