public function CartEventSubscriber::cartAdd in Mailchimp E-Commerce 8

Respond to event fired after adding a cart item.

Initial cart creation in Mailchimp needs to happen when the first cart item is added. This is because we can't rely on the total price being available when the Commerce Order itself is first created.
