Error with recent websockets package

[jiargei]

Running hbmqtt I get the following error.

Traceback (most recent call last):

from websockets.protocol import WebSocketCommonProtocol
ModuleNotFoundError: No module named 'websockets.protocol'

Current Workaround:

sed -i 's/from websockets.protocol import WebSocketCommonProtocol/from websockets.**legacy.**protocol import WebSocketCommonProtocol/' ~/.local/lib/python3.9/site-packages/hbmqtt/adapters.py

The change was made in websockets v 9.0, so version 8.1 is the last one that works by default

Facing this error message with newly created virtual env:

Traceback (most recent call last):

ImportError: cannot import name 'WebSocketCommonProtocol' from 'websockets.protocol' (/opt/anaconda3/envs/test/lib/python3.10/site-packages/websockets/protocol.py)

Looks like the dependency on websockets is not bound with, and causes error whenever install this package.
