Compute price for a set of specified products

POST https://{merchant}.fulfil.io/services/channels/v1/product/compute-prices

This endpoint will return the product price based on the products and customer specified

Works with both formula and product pricelists

1. When the customer value is not provided, the channel price list is used
2. When the customer value is provided, the price list on the customer account overrides the channel price list (if defined)
3. Quantity is optional (Defaults to 1), UOM is optional (defaults to sale uom on product)
