Fix comments

Browse source 
The YouTube headers are now always added for requests to YouTube.
Previously they were only added for requests going through QUIC.

The session token is now JSON decoded to unescape escaped Unicode characters.

The comment continuation protobuf has been updated and the request now goes
through the YouTube `pbj` JSON API.
