Create simple streaming example in README

[recursionbane]

Hi, this is a great project, thank you for creating it.

I see that you have a nice, simple example for transcribing a prerecorded audio file.

Looking through the sample app, it seems there are a lot of steps needed to get the transcription of an ongoing recording streamed out.

Can you please provide a simple streaming recording+transcription example in the README, similar to the current transcription example?
