Feature Request: Reconnect Exponential Backoff - 功能请求：重新连接指数退避

[ajslater]

It would be nice to have the reconnect algorithm do exponential backoff to prevent clients from flooding the server.
如果重新连接算法能够进行指数退避，从而防止客户端淹没服务器，那就太好了。

Example 例子

const EXPONENT_BASE = 1.15; // 指数基数

reconnect(): void {
    // 已重连次数小于等于设置的连接次数时执行重连 | Reconnect when the number of reconnections is less than or equal to the set connection times
    if (this.reconnectionCount <= this.reconnectionAttempts) {
      this.reconnectionCount++;
      let reconnectionDelay;
      if (this.reconnectionExponentialBackoff) {
        const multiplier = (EXPONENT_BASE ** (this.reconnectionCount -1));
         reconnectionDelay = this.reconnectionDelay * multiplier;
       } else {
         reconnectionDelay = this.reconnectionDelay;
      }

My example, 1.15, is just a suggestion but it would lead to:
我的示例 1.15 只是一个建议，但它会导致:

reconnectionCount	multiplier
1	1
2	1.15
3	1.3225
4	1.520875
5	1.74900625
6	2.01135719
7	2.31306077
8	2.66001988
9	3.05902286
10	3.51787629
11	4.04555774
12	4.6523914
13	5.35025011
14	6.15278762
