add another effect.

Hi, your overscroll is so great, and I add another effect to make it better.

It's easy to use:
OverScrollDecoratorHelper.setUpScaleOverScroll(recyclerView,OverScrollDecoratorHelper.ORIENTATION_HORIZONTAL, 2);
2 is the value of damping, the bigger the value, the harder it is to slide

here is the gif

I add this effect in your demo, this effect can perfect fit all these examples. You can see the new effect by click "switch effect"

I hope you can accept my code.
Thank you very much.

NestedScrollView can't overscroll, when it has a child recyclerView. @lk5103613
