Add more websockets implementations

[AdrianEddy]

• [x] fastwebsockets
• [ ] ws-tool (Panicked when tested)
• [x] soketto
• [ ] websocket.rs (Doesn't provide handshake)
• [ ] wsocket (There is no instruction or example about usage)
• [ ] uwebsockets-rs (It is preferable to use the original C++ project)
