Comment extraction improvements

[neon-ninja]

This PR fixes the comment scope to prevent incorrectly extracting comments from related posts.
It also adds the ability to extract replies - threaded comments inline. These show up as a replies list within the top level comment. Sample output:

[{'available': True,
  'comments': 0,
  'comments_full': [{'comment_id': '3246783635424072',
