设置本地内购页路径

如果需要使用本地内购页，当Session汇报返回时，会拿到本地内购页ID，这个
ID须作为本地内购页包名

网页端创建本地内购页，同时要将生成的内购页
ID作为内购页包名，把内购页包放入项目中

//nativePaywallId: 内购页包名
let nativePaywallPath = Bundle.main.path(forResource: "index", ofType: ".html", inDirectory: nativePaywallId)
DYMobileSDK.loadNativePaywall(paywallFullPath: nativePaywallPath, basePath: Bundle.main.bundlePath + nativePaywallId)

//nativePaywallPackage： 内购页包名
NSString *nativePaywallPath = [[NSBundle mainBundle] pathForResource:@"index" ofType:@".html" inDirectory:nativePaywallPackage];
NSString *basePath = [NSString stringWithFormat:@"%@%@",[[NSBundle mainBundle] bundlePath],nativePaywallPackage];
[DYMobileSDK loadNativePaywallWithPaywallFullPath:nativePaywallPath basePath:basePath];
