Added "inventory_sku" field to OrderItem and Warehouse Fulfillment Item resources. Currently, the SKU field on the order item is based on the SKU of the found on the listing associated with that item. However, these SKUs may not always be the same SKU found on the associated inventory. This new field will clear any confusion of whether the SKU found on the original "sku" field was the same value found on the listing or on the inventory.
