pinger PING工具

支持IPv4和IPv6地址，用于探测目标主机是否活跃。

Example1: 探测主机是否活跃

    rtt:=pinger.IsAlive("www.baidu.com")
    if rtt > 0 {
        // it is alive
    }

Example2: 高级使用

    p := pinger.New()
	p.OnRecv=func(r *pinger.ReplyInfo) {
        // handling
	}
    p.Ping(net.IPv4(192, 168, 10, 5), 200)
    // 如果要提前中断Ping则调用 `p.Interrupt()`
