Implement chapter support

You can define and track custom chapters for video tracking in TVSDK-based applications.

Custom chapters are managed by the application, and are based on CMS data or on another way that the application uses to define chapters.

1. Define and track custom chapters.

   // First, enable chapter tracking by setting
   // enableChapterTracking to true:
   
   vaMetadata.enableChapterTracking(true);
   // For custom chapter definitions, provide
   // an array list of chapters through the metadata.
   // For example: 3 chapters of 60 second duration each
   
   List<VideoAnalyticsChapterData> chapters =
     new ArrayList<VideoAnalyticsChapterData>();
   
   Int chapterDuration = 60;
   for (var i = 0; i < 3; i++) {
       VideoAnalyticsChapterData chapterData =
         new VideoAnalyticsChapterData(i * chapterDuration, (i + 1) * chapterDuration);
       chapterData.setName("chapter_" + (i+1));
       chapters.add(chapterData);
   }
   
   vaMetadata.setChapters(chapters);
