Receive a 32-bit Integer from a Socket

Demonstrates Socket.ReceiveInt32, which reads exactly four bytes as a signed 32-bit integer and stores the result in the ReceivedInt property. Byte order is selectable.

Background. Fixed-size integers and length prefixes are common building blocks for application-defined binary protocols. Byte order is selectable, with big-endian being network byte order.
