The existing single-message parser tests can pass even if the parser doesn't fully consume a message (e.g., missing a null terminator), because there's no subsequent message whose parsing would be corrupted. These chain tests concatenate multiple messages into a single buffer and verify the parser correctly advances through each one. Adds a property-based test with a generator covering all 26 parseable message types (random sequences of 2-8 messages, verifying each parse yields non-None and the buffer is fully consumed), plus 7 example-based tests covering realistic protocol sequences with field-level assertions: SimpleQueryResult, CopyOutSequence, EmptyQuerySequence, PrepareSequence, CloseStatementSequence, SASLFullSequence, and RemainingTypes. Resolves the TODO at the former line 6 of _test_response_parser.pony.
