Fixed issues when compiling for watchOS, with SPM, Xcode 12, and / or Swift 5.3+.

This update includes some changes and improvements that will (hopefully) fix some common issues as well as expand support for long-awaited features.

New Features

• watchOS support. Apple has introduced in-app purchases on the Apple Watch starting with watchOS 6.2. Now you can use SwiftyStoreKit to take advantage of this additional platform.
• Discount support. Now your app can offer in-app purchase discounts to users through SwiftyStoreKit (#458).
• Cancellable requests. Attempt to cancel requests sent with SwiftyStoreKit.

Improvements & Bug Fixes

• Sandbox purchasing process should be improved. New checks exist to help you identify when a request is being sent in the sandbox and to isolate sandbox-specific errors.
• Added Purchased protocol to create common conformance for Purchase, PurchaseDetails, and ReceiptItem.
• Fixed callback issues when restoring items.
• Added a new API to retrieve all product identifiers, getDistinctPurchaseIds.
• Extended support for your own receipt verification process.
• ReceiptItem now conforms to Codable.
• Additional extensions on existing StoreKit classes for localizedSubscriptionPeriod, localizedPrice, and localizedDiscountPrice.

• The project should now correctly compile for macOS Catalyst

• Update project to Swift 5 (#457), related issue: #456
• Add basic SwiftPM manifest file (#460)

• Add missing else condition in SwiftyStoreKit.purchaseProduct (#426)

• Added new property isInIntroOfferPeriod to ReceiptItem (#404, #409)
• Add Swift 4.2 Support (#408), update project to Xcode 10 (#410)

• Fix macOS compile error on Xcode 10.0 beta (10L176w) (#381, see #380)
