* New: Included a new collector module to allow inclusive ( AND ) for advanced category rules. Since this is a unusual use case a filter is needed to enable.
-- add_filter('wc_dynamic_pricing_get_collector_object', function($collector, $type) { return 'WC_Dynamic_Pricing_Collector_Category_Inclusive'; }, 10, 2);
* Fix: Include check that categories have been selected before attempting count.
