Update python-socketio to 1.8.0

[BertrandBordage]

I’ve been through a lot of issues others also faced: 400 & 500 errors, “Invalid frame header”, “Opcode -1” and memory leak.

I also had an issue with one of the latest changes of this project: the ignore_queue argument that was passed to python-socketio, but since I was on an old version (1.6.0), it was not handled correctly, randomly triggering 500 errors.

After updating to python-socketio 1.8.0, all these issues were resolved.
So setup.py has to be updated to require at least python-socketio 1.8.0.

I agree regarding ignore_queue, I should have bumped the requirements. But that came in the 1.6.1 release of the Socket.IO server. Were there any other issues that required going to 1.8, or was that the only release that you tested?

[BertrandBordage]

It’s the only version I tested.
