I miss the localised subtitle properties subtitle-loc-key and subtitle-loc-args because you're using old Apple documentation

Thanks for this great lib.

The detailed apn.Notification documentation refers to the Apple payload documentation at https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CreatingtheNotificationPayload.html

This link is outdated, the modern docu can be found at https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/generating_a_remote_notification
In particular Table 2 is important, as it shows a set of new keys which is not present in your Convenience Setters.
Among them the subtitle and it's localised variants; subtitle-loc-key and subtitle-loc-args.

Would it be possible to add these and other missing ones and update your documentation?
