Execution example in the readme raises an error

[s-wel]

The code example in the readme raises an error for me
AttributeError: 'HiveMessageBusClient' object has no attribute 'protocol'.
After trying a bit, I managed to get it working by changing the code like this:

bus = HiveMessageBusClient(key, password, host, useragent="xclientx")
bus.connect()

I removed crypto_key and added password instead, added the host (only my case) and added a bus.connect(). When executing the code with these changes, I get a series of log messages including one with the response message and an error that the websocket was already open (does not stop the script). I suggest adding the changes above to make the example work.
