这里贴一段代码是计算偏移量的应该是（FeakHead）
还是没有找到下载的MasterData和第一个ab包
https://asset.lecisxqw.com/amgameasset/Stg/AssetBundles/Android/9A188D7BF0BF119DE38B57A44DF3A917.ab
的解密逻辑（恼
这个偏移量计算函数在
void Pyro_AssetBundleManager_AssetBundlesLoader__LoadAssetBundleFlow_d__41__MoveNext(
Pyro_AssetBundleManager_AssetBundlesLoader__LoadAssetBundleFlow_d__41_o *this,
const MethodInfo *method)
被调用（使用1.0版本做的分析新版1.01懒得再重新分析了）
从代码中可以看到对文件名进行了md5加密而下载的文件命名也确实是md5作为文件名
图随便截的函数中一个获取MD5的地方这个函数足足有715行代码。。。应该是AssetBundle加载的核心
