Implement SendData

SendData should be an implementation of Arrow Flight's DoPut function.
It should take input from a file, and send the data to a flight server, which is then processed by the server, returning a PutResult.
The first message of the function should be a FlightDescriptor.

**Issue originally raised by Aidan Kovacic.**

Read the Arrow Flight specification to understand the DoPut protocol. Look at the existing codebase for other Flight command implementations to see the pattern. The function needs to read from a file, send a FlightDescriptor as the first message, stream data to a server, and handle the PutResult response. Check for any existing tests for similar commands to understand the expected behavior.
