Error in Readme example execution

[Leobouloc]

I get the following error when running the example in the README:

>>> wss.conn.wait()
Traceback (most recent call last):

  File "<ipython-input-6-972ef3cfd4a6>", line 1, in <module>
    wss.conn.wait()

AttributeError: 'WebSocketConnection' object has no attribute 'wait'

If I replace this line by a time.sleep(60), i get the following error:

>>> wss.subscribe_to_ticker('BTCUSD')
ERROR:btfxwss.client:Cannot call subscribe_to_ticker() on unestablished connection!
INFO:btfxwss.connection:Connection Error - [Errno 110] Connection timed out
INFO:btfxwss.connection:Connection closed
INFO:btfxwss.connection:Attempting to connect again in 10 seconds.
INFO:btfxwss.connection:Connection opened
INFO:btfxwss.connection:Connection closed

Any ideas ?

while not wss.conn.connected.is_set():
    time.sleep(1)

Hey, 60s is way too long, you probably have a timeout before you even try to subscribe. Those two lines achieve what is actually intended.
