Allow parsing PROX packets with length prefix

The PROX version is special in that it has custom data after the first 9 bytes of the connection IDs. That means that trying to parse it with length prefix as an unknown QUIC version means that a random payload byte can be interpreted as the source connection ID length. This CL makes parsing succeed in that case, ignoring the source connection ID. This allows a previously existing test to pass.
