Abandoned Cart Addon – Persistent cart sync for guests

At the moment the Abandoned Cart addon can sync an updated cart to ActiveCampaign or Drip when a registered user adds a new item to the cart or updates an existing cart item quantity, however this does not work for guests.

Guests need to return to the checkout page and re-enter their email for the updated cart to be synced to the CRM.

Todo: Create some kind of system for tracking guests outside of the checkout page, so that changes to the cart contents are synced to the CRM automatically (without needing to revisit the checkout page).
