 I'm sure there's way more efficient ways to do this, but for me this works so far and it's my little baby.

+# Usage instructions and example
+1. Import the script in to your project
+2. When you want to load you can call the class:
+```
+var music = AudioStreamPlayer.new()
+var audio_loader = AudioLoader.new()
+music.set_stream(audio_loader.loadfile("/path/to/song.ogg"))
+music.volume_db = 1
+music.pitch_scale = 1
+music.play()
+```

 ### TODO:
 
 0. Test with very different wav files in order to see if format parsing works for different chunk sizes (doesn't seem to)
