Description of the change

Added InstabugWidget, a wrapper used to wrap the main application to provide out of the box automatic Crash Reporting support.

Example:

void main() {
  WidgetsFlutterBinding.ensureInitialized();

      Instabug.init(
        token: 'APP_TOKEN',
        invocationEvents: [InvocationEvent.floatingButton],
        debugLogsLevel: LogLevel.verbose,
      );

  final app = InstabugWidget(
    child: const MyApp(),
  );

  runApp(app);
}

@MoKamall This PR seems to include more changes than intended. It should focus solely on adding the InstabugWidget wrapper, but it also contains commits related to the network body size and crashes. Could you separate the necessary commits to make it easier to review?
