Updated README with the fix on the error __on_error() takes 2 positional arguments but 3 were given

When I tried to do the setup from README, on different machines I kept on getting error __on_error() takes 2 positional arguments but 3 were given. I resolved it by installing websocket-client with pip install -U websocket-client

Getting a slightly different error message, i guess it has nothing to do with websocket?

TypeError: __on_open() takes 1 positional argument but 2 were given
