Give client a Python interface about deepspeech-websocket-server

[daanzu]

Sure; good idea, and a PR would be great! Actually, I have some cleanup to commit for the client that might help, which I'll try to complete in a day or two.

@TMiguelT Cleanup complete. Also refactored some to ease external usage.

if you could clearly describe about this issue, I will be very happy to become a contributor to this repo.

@daanzu, thanks for the cleanup!

I still believe there is some work that needs to be done though. The main thing this needs is the ability to import the client in another python package (@imkkk). For instance:

from deepspeech_websocket_server.client import Client

def callback(recognition):
    print(f"Recognised {recognition}")

Client().recognise(callback)

This would allow us to use the great VAD + DeepSpeech integration in another application, for example a custom web application.

I've slowly started looking into making a PR for this though, so don't stress if none of you get the chance to do this.
