What kind of issue is this?

• [ ] Question. If so, declare clearly your target and your current implementation with code formatted in markdown.

• [ ] Bug report. If so, please supply the way to reproduce the issue, including addition information as follow:

  • [ ] Toro version.
  • [ ] Android version (can be found in Device info). Rooted/Custom rom devices are not supported.
  • [ ] Device name (eg: Nexus 5X, Samsung Galaxy S8)
  • [ ] Source code that can reproduce the issue (a snapshot is expected).
  • [ ] Logcat stack trace in case of fatal issue.

• [x] Feature request. Start by telling me what problem you’re trying to solve. Don’t send pull requests to implement new features without first getting my support. Sometimes I leave features out on purpose to keep the project small.

• [ ] Other. Senseless issues are normally ignored. Please understand and cooperate.

implementation(
      "com.google.android.exoplayer:extension-ima:${rootProject.ext.exoPlayer2Version}") {
    exclude group: 'com.android.support'
  }

The dependency increases whopping 1.7 MB of APK size with proguard on, and I don't think this should be added in as a dependency to the toro-exoplayer. It should be a peer dependency which other people can install if they want the extension's support

This is reasonable, will consider this real quick.
