Integration of new_or_returning_customer Shopify order level dimension#1507

Hi there,

I’d like to request a new dimension integration for the Shopify API.
Is the new_or_returning_customer, a label specifying whether an order is from a new or returning customer.
This will be available at the order level / table.

For the sake of clarity, this is not the same thing as issue #1054
The dimension cited in #1054 is available on customer table.

Thanks,
Matteo
