Support socketio server v3 and v4

[tommy19970714]

In the following issue, he says that v2 of socketio server is not supported and v3 and v4 are supported, but when I tried it, it works with v2 but not with v3 and v4.
#16

I referred to the test code, but this project has been tested only with v2.

As noted below, there seems to be a disruptive change in socketio v2 and v3.

Can you support v3 and v4 of socketio server?

At the moment, I do not use this library in my projects, so I provide support as I have free time.
It will help me a lot if you provide me with js code for simple servers for each version of Socket.IO. This way I can create local tests and make the client work.
