Update websocket library.

[pavoni]

The library we were using was very old - and was stale for a long time.

But the great news is that https://github.com/websocket-client/websocket-client is now active - and has several years worth of bugfixes!

I'm hopeful it will close #54

This will require some testing!

@doctorfree Do you have a view on this?

I'm tempted to merge and release a version using the new library - since it makes it easier to test in HA.

But don't want to mess up you or users of https://github.com/doctorfree/RoonCommandLine

I don't have a very good understanding of the changes involved in moving to the newer WebSocket client for Python. My initial impression is this would not impact RoonCommandLine. Regardless, my view is to improve the Python Roon API library and I will adjust accordingly as necessary.

Thanks - I guess it’s mostly just a pretty big version change - so perhaps risky.

I’ll do some more testing, it did work out the box though.

Once it looks good - I’ll build a library - and ask you to check it out.

This is already looking good. It recovers reliably to a local roon core on my dev machine - which I can't get the old library to do.
