Updating commands and Packet API

- Added wrapper for PacketHandshakeInSetProtocol
- Took ProtocolAPI from Atlas to implement ViaVersion and ProtocolSupport version checking hooks.
- Added hook into "Login" style packets.
- Wth this new hook, we get player version numbers and store them by Channel now.
- Packets are now initialized in the same join listener as where APlayer is generated in JoinListener class.
- Removed Listener extension from HandlerAbstract, ModernHandler, LegacvHandler

NOTE: Protocol version grabbing needs implemented for LegacyHandler (1.7.10 version)
