Xcode 12 and iOS 9.0 various deprecation

[michaelsogos]

Dear all,

With Xcode 12 and iOS 9.0 seems that a lot of methods to play with status bar have been deprecated, like:

cordova-plugin-statusbar/CDVStatusBar.m:389:14: warning: 
      'setStatusBarHidden:' is deprecated: first deprecated in iOS 9.0 - Use -[UIViewController prefersStatusBarHidden]
      [-Wdeprecated-declarations]
        [app setStatusBarHidden:NO];

cordova-plugin-statusbar/CDVStatusBar.m:267:56: warning: 
      implicit conversion loses integer precision: 'UIStatusBarStyle' (aka 'enum UIStatusBarStyle') to 'int' [-Wshorten-64-to-32]
        vc.sb_statusBarStyle = [NSNumber numberWithInt:style]

cordova-plugin-statusbar/CDVStatusBar.m:271:44: warning: 
      'setStatusBarStyle:' is deprecated: first deprecated in iOS 9.0 - Use -[UIViewController preferredStatusBarStyle]
      [-Wdeprecated-declarations]
        [[UIApplication sharedApplication] setStatusBarStyle:style];

Even if are warning, the build fail 'cause Project POD is automatically configured to raise error also when encounter warnings. For now I will resolve this playing with Xcode build flags thank to build.json (I hope 🤞).

In the mean time can you play with a new major version (in order to leave 2.x as it is for older projects) which solve above issues?
