 * TIPS:
 * - If you want to force every file to be downloaded, you can hook the $mime_types variable and return an empty array
 *   and set the shortcode parameter my_doc_viewer="library-viewer"
 *     Example Code:
 *   add_filter('lv_mime_types', function(){
 *       return array();
 *   });
 *
 * - If you want to force files with specific extension to be downloaded, just unset the value from the array.
 *   Example Code:
 *   add_filter('lv_mime_types', function($mime_types){
 *         unset( $mime_types['pdf'] ); //force only pdfs to be downloaded
 *         return $mime_types;
 *   });
