Add snapshot picture to push notifications

[Aaron]

Pictures in push notifications are supported by both Android and Apple (iOS 10). This would be very helpful.

@aaron Hi Aaron, thank you for the suggestion. We plan to add thumbnails to push notifications in a future update. Stay tuned!

@reolink-lorenz Do you have a timeline for this update?

This would make push notifications useful - as it is, by the time you see it and open the app, you've got no idea what was seen, and would have to go hunt through recordings for that timestamp.

I don't use Push Notifications with Reolink due to this missing feature.
