Marked As Played Added To Stats

### Description

I would like to suggest adding podcasts that are marked as played to the stats data, expanding from just the duration of podcasts that have been listened to within the Pocketcast apps.

Before the web player was opened to all users I listened to podcasts on a different program at times. Adding these podcasts into the stats would be fantastic.

- [x] I have searched for existing issues.

No files, tests, or entry points are named in the issue. Start by locating the Android stats data flow and the handling of episodes marked as played; done means those episodes are included in stats, including listening completed outside Pocket Casts.
