Bento Enhanced Ecommerce

Add support for Bento to the Enhanced Ecommerce addon (https://wpfusion.com/documentation/ecommerce-tracking/ecommerce-overview/) Sync order data, coupons, and line items as an event. As much as possible it should be compatible with the way Bento already tracks events for WooCommerce orders (https://github.com/bentonow/bento-wordpress-sdk/blob/master/inc/orders.php)
