[storefront-api-client] Use "Shopify-Storefront-Buyer-IP" with storefront-client

[zircxnium]

Hello there, I'm trying to using storefront-api as s2s and the API says that you need to use the Private Access Token combined with the Buyer IP when doing a request to the storefront API, however after digging into the storefront-client source code I didn't found any implementation of the buyer IP header and the examples showed using the Private Access Token does not use it too.

EDIT: I saw that you can add headers after variables when doing "storefront.request", is this the right way of doing it ?
