Flesh out support for the remaining Apple IAP Notification Types

[zspencer]

Currently, we support about half of the Apple In App Purchase notification types - https://developer.apple.com/documentation/appstoreservernotifications/notification_type

To start, we will want to add the remaining items to the Compensated::AppleIAP::EventParser::SUPPORTED_TYPES constant; and if we have example payloads add them to spec/apple_iap/fixtures and flesh out the expected data in the apple_iap/event_parser_spec
