Receive Text from a Socket into a StringBuilder

Demonstrates Socket.ReceiveSb, which receives text, decodes it using StringCharset, and appends it to a StringBuilder.

Background. Text send and receive operations encode and decode bytes using the StringCharset property. For plain ASCII or UTF-8 protocols, setting StringCharset to utf-8 is a safe default.
