/**
 * <pre>
 * 个性签名操作的回复包
 * 1. 头部
 * 2. 子命令，1字节
 * 3. 回复码，1字节
 * 
 * 如果2部分为0x00, 0x01，则
 * 4. 尾部
 * 
 * 如果2部分为0x02，即得到个性签名，则还有
 * 4. 下一个起始的QQ号，4字节。为这个回复包中所有QQ号的最大值加1
 * 5. QQ号，4字节
 * 6. 个性签名最后修改时间，4字节。这个修改时间的用处在于减少网络I/O，只有第一次我们需要
 *    得到所有的个性签名，以后我们只要送出个性签名，然后服务器会比较最后修改时间，修改过的
 *    才发回来
 * 7. 个性签名字节长度，1字节
 * 8. 个性签名
 * 9. 如果有更多，重复5-8部分
 * 10. 尾部
 * </pre>
