v4.0.0

• Major: Removed support for chat rooms. Attempting to join a Twitch chatrooms: channel will result in a validation error.
• Minor: Added flags and flagsRaw properties to PrivmsgMessage and UsernoticeMessage classes, allowing inspection of AutoMod message rating results. (#38)
• Minor: Added parsing support for newer usernotice parameters (msg-param-gift-months, msg-param-sender-count)
• Bugfix (Potentially breaking, check your application): In subgift and similar USERNOTICE messages, recipientUserName is now correctly camelcased as recipientUsername as was documented.
• Bugfix: Emotes occurring after emojis are now correctly parsed (#35)
• Bugfix: Messages with wrong emote indices (sent by Twitch) are now handled gracefully instead of failing the message parser. (#22)
