Create StringeeClient

` javascript
import { StringeeUtil, StringeeClient, StringeeCall, StringeeCall2 } from "stringee";

const client = new StringeeClient();

client.on("connect", () => {
// connected to StringeeServer
});

// on authen user, response object
// {
// r : 0
// requestId : 1
// clients : [{…}]
// connectionId : 123456789
// ping_after_ms : 45000
// projectId : 1234
// userId : "abc"
// ice_servers : [{…}, {…}, {…}, {…}]
// message : "SUCCESS"
// }
// response success: r = 0
// response error: r != 0 and message : "Error message"
});

client.on("disconnect", () => {
//disconnected
});

client.on("incomingcall", (incomingcall) => {
// Setup voice call
});


client.on("incomingcall2", (call2) => {
// Setup video call
});

client.on("requestnewtoken", () => {
// request new token;
// please get new access_token from YourServer
// and call client.connect(new_access_token)
});

client.on("otherdeviceauthen", (data) => {
console.log("otherdeviceauthen: ", data);
});

// HANGUP
call.hangup((res) => {});
// at the same time we remove all video tracks

// MUTE
call.mute(true);

// SEND INFO

// ENABLE/DISABLE VIDEO
// disable Local Video

// SWITCH CAMERA (mobile only)

`javascript
