Receive a Bounded String from a Socket

Demonstrates Socket.ReceiveStringMaxN, which receives and decodes text like ReceiveString but reads at most a given number of input bytes.

Background. The limit is measured in bytes, not Unicode characters, so a byte limit can split a multibyte character or a protocol token. Decoding uses StringCharset.
