[ ENH ] Add support for streaming downloads

[jshcodes]

Add support for the stream keyword to all Service Classes and the Uber class.

The intended use case for this proposed enhancement relates to downloading large files from hosts using RealTimeResponse.

This keyword should be defined as a boolean and be provided to the requests library for all calls to the API.

More documentation regarding this keyword and it's usage can be found here.

Additional context As discussed in the Caracara repo.
