Receive Bytes into a BinData

Demonstrates Socket.ReceiveBd, which receives one delivery of binary data and appends it to a BinData. It returns whatever is immediately available.

Background. The BinData receive methods accumulate raw bytes in a BinData object. A single receive returns only what is currently available, whereas the counted receive waits for an exact number of bytes.
