/**
* <pre>
* 上传下载分组名字的消息包,格式为
* 1. 头部
* 2. 操作方式字节,如果为0x2,为上传组名,如果为0x1,为请求下载组名
* 如果为0x2,后面的部分为
* i. 组序号,qq缺省的组,比如我的好友,序号是0,其他我们自己添加的组,从1开始,一个字节。
* 但是要注意的是,这里不包括我的好友组,因为我的好友组是QQ的缺省组,无需上传名称
* ii. 16个字节的组名,如果组名长度少于16个字节,后面的填0。之所以是16个,是因为QQ的组名长度最多8个汉字
* iii. 如果有更多组,重复i,ii部分
* 如果为0x1,后面的部分为
* i. 未知字节0x2
* ii. 4个未知字节,全0
* 3. 尾部
*
* 这个包没有限制添加的组名叫什么,也没有明确规定第一个组必须是
* 我的好友组,这些规范需要在上层程序中实现。当然也可以不一定非要第一个组是
* 我的好友组,这些客户端的trick随便你怎么搞
*
* 每次上传都必须上传所有组名
