Receive Bytes as Encoded Text from a Socket

Demonstrates Socket.ReceiveBytesENC, which receives one delivery of binary data and returns it encoded as text using a named encoding.

Background. The ENC methods move raw binary data to and from printable text using a named encoding such as base64 or hex, which is convenient for logging or for handling binary data as strings.
