unitPriceMeasurement on Variants

[AK-Christoph]

Hi there! 

This was asked before, but it being one of the biggest pain points in our Shopify use, I still want to address this:

Could you please enable unitPriceMeasurement fields in the GraphQL or REST Variant API? Not being able to set this automatically really holds us back. It has been bothering merchants for years.

Thanks in advance!
