Receive Text up to a Match into a StringBuilder

Demonstrates Socket.ReceiveUntilMatchSb, which receives bytes until an exact byte sequence is found and appends the received text to a StringBuilder.

Background. The match string is encoded using StringCharset and compared byte-for-byte. The match may span multiple underlying network reads.
