initialize method

Future<void> initialize({ required String bannerAdUnitId, required String interstitialAdUnitId, int? maxInterstitialAdCount, required VoidCallback onSuccess, required VoidCallback onFailed, })

初始化广告SDK 在应用启动获取到网络权限之后调用 @param bannerAdUnitId Banner广告单元ID @param interstitialAdUnitId 插屏广告单元ID @param maxInterstitialAdCount 最大插屏广告显示次数，默认值为null @param onSuccess 初始化成功回调 @param onFailed 初始化失败回调
