跨平台的zip文件压缩处理，支持压缩解压文件夹
根据minizip改写的模块，需要zlib支持
输出的接口：
#define RG_ZIP_FILE_REPLACE 0
#define RG_ZIP_FILE_APPEND 1 //压缩文件夹目录，递归压缩
//szDir是需要压缩的目录，dstLevel是压缩的目录在压缩包里面的层次标识
//可直接指定""
//szZipFile压缩包的文件名
//replaceFlag指定替换或者是追加进压缩包
int DoZipDir(const char* szDir, const char* dstLevel, const char* szZipFile, int replaceFlag); //压缩单个文件，szFile是文件名，其它参数解析同上
int DoZipFile(const char* szFile, const char* dstLevel, const char* szZipFile, int replaceFlag); //解压缩文件
//szZipFile是需要解压的压缩包文件名
//指定需要解压到的目录，直接指定为""，解压至当前目录
int DoUnzip(const char* szZipFile, const char* szTargetDir); //从压缩包里面解压单个文件出来
//srcFileToExtract对应压缩文件时的dstLevel
//其它参数解析同上
int DoUnzipFile(const char* szZipFile, const char* srcFileToExtract, const char* szTargetDir);
本文仅仅提供封装的api，zlib库和info-zip请自行下载
其它涉及的代码可以下载minizip或者info-zip，推荐使用minizip，本代码是在minizip的基础上修改而来，支持跨平台
