python-binance/binance/websockets.py missing Ping/Keep-alive a listenKey every 30m timeout

[xiaods]

Describe the bug
I found the UserDataStream's keeplive function is missing in current websocket.py.
so after every one hour, binance WebSocket conn is invalid.

To Reproduce
Code snippet to reproduce the behavior:
see binance API docs:
https://github.com/binance-exchange/binance-official-api-docs/blob/master/user-data-stream.md#pingkeep-alive-a-listenkey

Expected behavior
add keepalive logic in websocket.py

Environment (please complete the following information):

• Python version: 3.6
• Virtual Env: native
• OS: Ubuntu 18.04
• python-binance version: 0.75

sample code

def initialize_arb():
          # ping user websocket every 30 minutes
    while True:
        get_margin_stream_keepalive(conn_key)
        time.sleep(60 * 30)

'''
Purpose: Keepalive a user data stream to prevent a time out. 
User data streams will close after 60 minutes. 
It's recommended to send a ping about every 30 minutes.
'''
def get_margin_stream_keepalive(listen_key):
    result = client.margin_stream_keepalive(listen_key)
    return result

I can confirm that UserDataStream stops sending updates after some time. This is definitely a bug in the framework

Here it works very well: https://github.com/oliver-zehentleitner/unicorn-binance-websocket-api

@xiaods Why did you close this? This issue is still happening.

I also encountered a problem in UserDataStream. Lost the websocket connection randomly. Is there any suggested workaround that we can check/ping the connection as a temp solution? Thanks!
