Issue summary

ℹ Apple introducing subscription promotional offer in iOS 12.2, it would help us winning back lapsed subscribers or retaining current subscribers, but SwiftyStoreKit hasn't support it yet. I can't pass a parameter with the type of SKPaymentDiscount to the api purchaseProduct(_ productId: String, quantity: Int = 1, atomically: Bool = true, applicationUsername: String = "", simulatesAskToBuyInSandbox: Bool = false, completion: @escaping (PurchaseResult) -> Void). I must realize another purchase process api via StoreKit to implement subscription promotional offer instead of apply the api in SwiftyStoreKit, It is weird.

What did you expect to happen

ℹ Please append the parameter paymentDiscount in purchaseProduct(_ productId:String, ... api and make subscription promotional offer available.
