Represents a message in the eth wire protocol, versions 66 and 67.

The ethereum wire protocol is a set of messages that are broadcasted to the network in two styles:

• A request message sent by a peer (such as GetPooledTransactions), and an associated response message (such as PooledTransactions).
• A message that is broadcast to the network, without a corresponding request.

The newer eth/66 is an efficiency upgrade on top of eth/65, introducing a request id to correlate request-response message pairs. This allows for request multiplexing.
