Adds ‘defer’ to google maps script

Hello @uriahs-victor,
You can exclude scripts from being loaded asynchronously using the following filter:

add_filter( 'sgo_js_async_exclude', 'js_async_exclude' );
function js_async_exclude( $exclude_list ) {
    $exclude_list[] = 'script-handle';
    $exclude_list[] = 'script-handle-2';

    return $exclude_list;
}

Best Regards,
