- Created an InternalPurchaseController. This coordinates the purchasing between provided purchase controllers and the internal purchasing mechanism.
- Removed StoreKitCoordinator and removed redundant files like PurchaseManager.
- Verification now happens before finishing a product.
- No longer checks for restored product after purchase. This means if someone repurchases a product they already have, it'll count as a transaction_complete. This shouldn't be happening anyway, but something to consider.

- Stops ASN1 files from being public/open.
- Fixes tests

- Stores every purchased transaction by product if the transaction date of the purchased transaction is greater than the last stored transaction. Then when getting the latest transaction it defaults to SK2 and checks it has a transaction date within the last hour. If that fails, then it gets the lastInternalTransaction, i.e. the transaction that caused the internal purchase controller to mark the transaction as purchased. Otherwise, we fallback to getting the last transaction whose date is within the last hour. If that fails, we wait 500ms before trying again and finally returning nil.
- When completing a purchase, a check is added that the productId of the purchase is the one being purchased. Also checks that the date of the purchase is within the last hour to stop old purchases from completing the purchase.
- Fixes tests and swiftlint
