Send a Single Byte over a Socket

Demonstrates Socket.SendByte, which sends one byte whose value is in the range 0 through 255.

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.
