[SSKR] Not needed Android resources included

Reporting this issue for SSKR lib but I believe this could be happening to the rest of the ecosystem.

There are certain Android resources in the android folder from SSKR lib that get included in the aar generated library and so included in the project that is using the file. These resources (mipmap, values, colors...) are not needed and they add some extra space to the APK. Launcher icon is overriding the one in the app using the library (if using the same name).

Also the manifest is specifying the allowBackup=true, which forces apps using the library to add a replace clause in the manifest.

I'm preparing a PR to fix this. I won't include the rest of the libs as it will require testing, and we don't have in place any project using the rest of the libs just yet.

從 SSKR 程式庫的 android 資料夾開始，檢查其資源和 manifest 如何封裝到產生的 AAR 中。驗證不必要的 mipmap、values 和 color 資源不再進入使用該程式庫的應用程式、啟動器圖示不會被覆寫，且 allowBackup 不會強制加入 manifest 取代條款。
