[Feature] Replace Anko Library

[kunzef]

I am just starting to work on #1527 and would like to remove Anko and replace it as Anko has been archived since 2020 (GOODBYE.MD). Currently we are using Anko mostly for the AlarmManager and NotificationManager as well as Threading and other support classes. The replacement of this should be fairly smooth as the Kotlin Support has developed and we are already using jetpack in the app.
