python3-engineio: now depends on simple-websocket

[FederAndInk]

engineio now depends on simple-websocket since version 4.7.1
it doesn't seem to be specified in the recipe.

I've looked at the code a little bit. It seems that the simple-websocket dependencies is as optional as request or websocket-client. ie without it, you can still run the package in other modes (client or server, gevent or something else...)

Maybe you can:

1. ask the python-engineio project if simple-websocket is really a required dependency or an optional one.
2. put the optional dependencies (simple-websocket, request, websocket-client) behind PACKAGECONFIG
