Waze Integration

### What problem does this address?

In Waze, there exists the ability to play audio directly from Waze such as Spotify or Audible. There are only a few podcast apps available here. Currently, to play podcasts I must have the Pocket Casts playing separately from Waze. It would be helpful to have podcast navigation straight out of Waze rather than needing to pull up the audio player via the Notification shade or the app itself.

### What is your proposed solution?

Add Pocket Cast integration to Waze to play/pause/scrub directly in the Waze itself.

### Did you search for existing feature suggestions?

- [X] I have searched for existing feature suggestions.

Start by reviewing the Android project's existing media-control and external-integration entry points, then investigate the Waze integration requirements for podcast playback. Done means Pocket Casts can play, pause, and scrub from within Waze without requiring the notification shade or the app itself; the issue names no files or tests.
