Simplify interactions with arrow flight APIs

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
The current APIs are functional and with some source code digging, you can use them to accomplish your goals. However, I think it would be fair to note that they are not so convenient or easy to use as the comparable Python (or other language) implementations. Particularly on the client side.

Describe the solution you'd like
Extend the existing basic implementation and make it easier for developers to work with Flight in rust. Some ideas include:

• constructors for important types
• support for useful traits (e.g.: From, Display) for important types
• restrict access to "untyped" data (e.g.: Vec) and provide more typing

Describe alternatives you've considered
Look at the existing C++/Java/Python implementations for inspiration

Additional context
It should be as simple to create Flight client/servers in rust as it is in C++
