VEX-6030: Reduce buffer size based on heap (#13)
This PR changes the behavior on old devices that have poor memory management.

Jira: VEX-6030
https://jira.tenkasu.net/browse/VEX-6030

The solution implied customizing the method shouldContinueLoading from RNVLoadControl to use only the available heap, performing tests on an old Nexus 5 it was determined the ideal bytes allocation to half the reported heap, that provided some buffering during ads but smooth playback during the video with no crashes (23:39 of 23:39 at the moment of writing this, video kept playing as expected after 3 ad breaks)

The fix is only targeting Marshmallow as the reduction of buffer is substantial and other versions that work properly should not get affected.

Depending on the test result of VEX-5758, this same fix can be applied to Nougat

react-native-video - ExoPlayer

This is an Android React Native video component based on ExoPlayer v2.

ExoPlayer is an application level media player for Android. It provides an alternative to Androids MediaPlayer API for playing audio and video both locally and over the Internet. ExoPlayer supports features not currently supported by Androids MediaPlayer API, including DASH and SmoothStreaming adaptive playbacks. Unlike the MediaPlayer API, ExoPlayer is easy to customize and extend, and can be updated through Play Store application updates.

        ...
        disableFocus={true} // disables audio focus and wake lock (default false)
        onAudioBecomingNoisy={this.onAudioBecomingNoisy} // Callback when audio is becoming noisy - should pause video
        onAudioFocusChanged={this.onAudioFocusChanged} // Callback when audio focus has been lost - pause if focus has been lost
      />
    )
  }

  onAudioBecomingNoisy = () => {
    this.setState({ pause: true })
  }

  onAudioFocusChanged = (event: { hasAudioFocus: boolean }) => {
    if (!this.state.paused && !event.hasAudioFocus) {
      this.setState({ paused: true })
