[marcolanaro]

Some safari browsers are buggy and set some bits without negotiating them with the server.
This cause the server crash with:

code: "WS_ERR_UNEXPECTED_RSV_2_3"
message: "Invalid WebSocket frame: RSV2 and RSV3 must be clear"
stack: "RangeError: Invalid WebSocket frame: RSV2 and RSV3 must be clear
    at Receiver.getInfo (/app/node_modules/ws/lib/receiver.js:176:14)
    at Receiver.startLoop (/app/node_modules/ws/lib/receiver.js:136:22)
    at Receiver._write (/app/node_modules/ws/lib/receiver.js:83:10)
