[Feature] Add progress indicator that behave like VideoPlayerProfressIndicator

[gmr-renato]

VideoPlayer original package has VideoPlayerProgressIndicator that offers a great drag controller for small videos like TikTok and Reels timeline.

I tried to switch from the original package to this one, but without a VideoPlayerProgressIndicator my TikTok-like timeline loses functionality. I was expecting something like this:

  CachedVideoPlayerPlusProgressIndicator(
    videoPlayerController,
    allowScrubbing: true,
    padding: const EdgeInsets.all(8),
    colors: VideoProgressColors(
      playedColor: Colors.white,
      bufferedColor: Colors.black.withOpacity(0.4),
      backgroundColor: Colors.black.withOpacity(0.8),
    ),
  );
