UnifiedPush support for push notifications

[th0mcat]

UnifiedPush is a way to use self-hosted services like ntfy to send push notifications to Android apps. Having the ability to do this with my current infrastructure and not have to rely on FCM would be very nice.

The kinda caviot is due to billing of in app purchases sync for lemmy is VERY dependent on google play services. You probably wouldn't be able to use any paid features of sync for lemmy on degoogled versions of android (even with microg). I also doubt lj is going to make a sync pro version of lemmy outside the playstore and setup his own billing system (sync isn't a open source project).

Another issue regarding unified push is lemmy doesn't have any great ways for thirdparty apps to use push notifications. Currently the only way to get push notifications is setting up a server which polls for new messages every min (similar to how sync for lemmy checks for new messages every 60 min by default). This would be massive resource hog for both instances and sync servers (memmy devs for instance, using frequent polling for push reported that just 800 users utilizing push equated to 1-3gb of bandwith). Further developement would require lemmy to support a more efficient means like Web Push API, web hooks, etc
