短信分割算法（以长度分割）
/**
* 以给定的 LENGTH 分割短信内容，返回分割后的字符串数组
* 以下是返回内容示例：
*
*
* sSMS = “abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz”;
* 1. 分割后的短信个数 < 10
* LENGTH = 10;
* (1/6)abcdefghij
* (2/6)klmnopqrst
* (3/6)uvwxyzabcd
* (4/6)efghijklmn
* (5/6)opqrstuvwx
* (6/6)yz = 7
*
* 2. 分割后的短信个数 >= 10
* LENGTH = 5;
* (1/15)abcd
* (2/15)efgh
* (3/15)ijkl
* ......
* (13/15)tuv
* (14/15)wxy
* (15/15)z
*
*
* @param sSMS
* 短信内容
* @param LENGTH
* 每条短信的长度
* @return 一组短信内容
