[BUG] Missing Android Auto external speaker support

[EmilJunker]

Describe the bug
When the Android phone is connected with Android Auto, sounds played with react-native-sound-player still come out of the phone's speaker instead of the connected external speaker.

To Reproduce
Steps to reproduce the behavior:

1. Connect your Android phone to a car with Android Auto. Alternatively, install the Android Auto simulator on your PC and connect your phone with that via ADB.
2. Play a YouTube video, a Spotify song or anything else on your phone and observe that the sound comes out of the car/PC speaker and not the phone's own speaker.
3. Now play a sound with react-native-sound-player and observe that the sound comes out of the phone's speaker ☹️

Expected behavior
Sounds played with react-native-sound-player should come out of the connected car/PC speaker when connected with Android Auto, just like sound output from any other app does.

Platform

• OS: Android

Additional context
I tried calling setSpeaker(true) but it had no effect of course since it's only for iOS.
