youtube_dl.utils.UnsupportedError: Unsupported URL: https://www.vlive.tv/post/0-18257176

Description

https://www.vlive.tv starting using two types of urls: https://www.vlive.tv/video/<videoId> (old) and https://www.vlive.tv/post/<postId> (new).

For example, http://www.vlive.tv/video/16937 and https://www.vlive.tv/post/0-18257176 both points to the same video.

While current version of yotube-dl supports old type, it returns Unsupported URL error when using new type.
