Send BinData Contents over a Socket

Demonstrates Socket.SendBd, which sends bytes from a BinData beginning at an offset. A numBytes of 0 sends from the offset through the end of the data.

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.
