Ink: Add `clear` method to clear output

[goliney]

I want to clear the screen before exiting.
This is what I tried:

app.rerender(<Box />);

But it doesn't work.

If I try to print an empty line with app.rerender(<Box>{'\n'}</Box>); it works, but I don't need an empty line.

Could you please give me a piece of advice?
