`onPlayerComplete` does not fire on Android when the player mode is low latency

Current bug behaviour

The player does not fire a completion event when the playback ends if the player is set in low latency mode. This can only happen on Android.

Expected behaviour

An event is fired in the onPlayerComplete stream when the player finishes the audio.

Steps to reproduce

1. Execute flutter run on the code sample
2. Click the "Play" button to hear a piano note.
3. If the completion event works, you should hear a second piano note.

Unfortunately this is by design due to limitations of Android Pool Player:
https://github.com/bluefireteam/audioplayers/blob/main/getting_started.md#player-mode
You should stop the player by yourself if you know the length of your audio sample or just reuse the player for playing the same audio multiple times.
