feat: make debug.deep more usable

[thymikee]

Summary

Make debug.deep more usable by allowing it to print arbitrary JSON (and actually any) files. This proves handy when we want to debug async component which we want to snapshot after async operations:

const { toJSON, getByName } = render(
  <Button onPress={jest.fn} text="Press me" />
);
fireEvent.press(getByName('TouchableOpacity'));
await flushMicrotasksQueue();

debug.deep(toJSON());
