fix video crashing on Android because of unresolved ExoPlayer breaking changes

[Buthrakaur]

This fixes video crashing on Android because of unresolved ExoPlayer breaking changes (mainly because of the new threading model https://developer.android.com/reference/androidx/media3/exoplayer/ExoPlayer#threading-model) https://github.com/NativeVision/viro/issues/229

Hello @robertjcolley , could you please review this and possibly release new react-viro version if all is ok?

I am reviewing this PR Edit: Unfortunately the crash persists, I will research further

[Buthrakaur]

Hello @doranteseduardo , could you please share your repro steps and reopen the PR so we can fix any remaining issue and make the video work in viro? I tracked this crash down and fixed in viro-starter-kit (build viro-code => build viro => copy AAR artifacts to viro-starter-kit => build and run viro-starter-kit) and integrated as a patch into our own app and changes in this PR definitely fixed the crashing video for me. We are actually already using this in production - see the screen recording here: https://drive.google.com/file/d/1Bf959n_cfSL8rkDweHGVfqARj4NZxUch/view?usp=sharing

• my viro-starter-kit test code:

const HelloWorldSceneAR = () => {
  const [text, setText] = useState("Initializing AR...");
  const [videoStatus, setVideoStatus] = useState<
    "playing" | "paused" | "finished" | "not ready"
  >("not ready");
  const [videoPaused, setVideoPaused] = useState(false);
  const videoRef = useRef<ViroVideo>();

  function onInitialized(state: any, reason: ViroTrackingReason) {
    console.log("onInitialized", state, reason);
    if (state === ViroTrackingStateConstants.TRACKING_NORMAL) {
      setText("Hello World!");
    } else if (state === ViroTrackingStateConstants.TRACKING_UNAVAILABLE) {
      // Handle loss of tracking
    }
  }

  return (
    <ViroARScene onTrackingUpdated={onInitialized}>
      <ViroText

        scale={[0.5, 0.5, 0.5]}

      />

Hello @doranteseduardo , any update? I spent quite some time with this PR so it's a bit demotivating to get the PR closed with no discussion or attempt to resolve any issues you discovered..

[doranteseduardo]

@Buthrakaur I am sorry for the late response, I have been reviewing requests from the users on Discord. I will get back to this later this week.

[doranteseduardo]

Update: I completely reviewed this PR and found that the issues I had before were not in here, but a bad build. My apologies.

Thanks so much for bringing this fix to us :)
