Migrate away from deprecated API on MacOS

Currently `NSUserNotifications API` is used on MacOS to display notifications. However this is marked as deprecated and should be replaced with `UserNotifications.frameworks API`. With the new API it is required to ask for permission before notifications can be send. The program will ask for permission to send notifications on the start.
