Cordova 9.0 support

[jorhel]

Hey!, your plugin is very great!.

I have used your plugin for the last year and it works great. But recently in version 9 of cordova it seems to not go so well in the new iOS resolutions and for some reason in cordova the icons do not appear in the compilation.

I hope you can support the plugin, it's very helpful.

Thank you very much for your time, dedication and effort.

I'm not an android expert, but I found where the icons where placed by cordova and copied them to the list.
