/**

 * 发送短消息的回复包，格式为：
 * 1. 头部
 * 2. 未知1字节
 * 3. 四个未知字节，全0
 * 4. 未知1字节
 * 5. 回复消息长度，1字节
 * 6. 回复消息内容，可能以0结尾，也可能不以0结尾，所以前面的消息长度并不可靠，还是应该以分隔符来判断
 * 7. 分隔符，1字节，0x01
 * 8. 接受者QQ号或者接受者手机号码。如果是QQ号，4个字节，如果是手机号码，最大18字节
 * 9. 如果是手机号码，则这里还有一个未知字节，0x00
 * 10. 回复码，如果是QQ号码，则回复码是1个字节，如果是手机号码，回复码是2个字节
 * 11. 如果是QQ号码，未知的1字节，如果是手机号码，未知的2字节
 * 11. 尾部
