get_video_comment() only returns 5 replies #7

From the documentation:

replies.comments[] A list of one or more replies to the top-level comment. Each item in the list is a comment resource.
The list contains a limited number of replies, and unless the number of items in the list equals the value of the snippet.totalReplyCount property, the list of replies is only a subset of the total number of replies available for the top-level comment. To retrieve all of the replies for the top-level comment, you need to call the comments.list method and use the parentId request parameter to identify the comment for which you want to retrieve replies.

I've addressed this in my fork by creating a new method get_comment_replies() that uses 'https://www.googleapis.com/youtube/v3/comments' instead of 'https://www.googleapis.com/youtube/v3/commentThreads' and takes the parentId as a parameter. The load_comments() method then calls this method if a topLevelComment has one or more replies.
