Updates the module to use the latest version of websocket-client.
WARNING:
It has been brought to our attention that there are issues with the license of the websocket-client package. This version of the websocket-client has been labelled as LGPLv2.1 where as previous versions were labelled with a BSD 3-clause license. The maintainers of that project are currently working to gain active consent from all contributors to switch future versions to an Apache 2.0 license. Once this license change has been implemented, this package will be updated accordingly.
As it has an LGPLv2.1 licensed library, version 0.9.2 of the mycroft-messagebus-client cannot be used in any other Mycroft project. We are however leaving the package available so that other projects can make their own decision on whether to use it or not.
