Adds a new MenuBar UI to the PurchaseTester app on macOS. The UI provides a quick utility to parse the local receipt and to check it against `/verifyReceipt`. This makes it super easy to debug receipts using PurchaseTester. <img width="859" alt="image" src="https://user-images.githubusercontent.com/3922667/214950089-3c6ad4c2-2ae1-4024-83a5-b1490eed9744.png">
