when connect to server，raise StopIteration

[AmazingRaise]

when connect to server, I got return

97:0{"sid":"cHjXNrXgO3JKL2rgAAAz","upgrades":["websocket"],"pingInterval":25000,"pingTimeout":60000}

however , socketIO-client raise StopIteration Exception.
I review the code , found funciton _read_packet_length in parsers.py, using ASCII to measure the length. That's the problem, I suppose.

def _read_packet_length(content, content_index):
if 'sid' not in content:
raise IndexError

val = re.findall('([\d]+)[:][\d]', content)
if val:
    content_index = len(val[0]) + 1
    return content_index, int(val[0])

while get_byte(content, content_index) != 0:
    content_index += 1
content_index += 1
packet_length_string = ''
byte = get_byte(content, content_index)
while byte != 255:
    packet_length_string += str(byte)
    content_index += 1
    byte = get_byte(content, content_index)
return content_index, int(packet_length_string)

It works, but I don't know what where happen

I found on server, the socekt.io version is 2.0.x, I think I should found the difference

[AmazingRaise]

socketio/socket.io#2833
socket.io(version 2.0.x ):Merge Engine.IO and Socket.IO handshake packets; so read the packet error.Need do something to void this

Likely relevant: #159
