Parsers

Clients are expected to implement all parsers, including properties (if any). If an unknown parser is encountered by a client, unpacking of the Declare Commands packet should stop immediately, as the structure of the remainder of the packet cannot be guessed.

In 1.19, Parsers are identified by a varint id. Pre-1.19, parsers are identified by a string id.
