this passes the attributes for the function "get_terms()"
Convenient for sorting, excluding taxonomy terms
For example, you want to sort terms by count
add_filter('avalon23_taxonomy_arg', function( $args ) {
if( $args['taxonomy'] == 'pa_size') {
$args['orderby'] = 'count';
$args['order'] = 'DESC';
}
return $args;
}, 99);
