Feature request: argument to change button size

[rempsyc]

I love copy-code buttons, and most of them are usually rather large (one example from the datawizard package is clearly visible). So I also love the klippy buttons but find them extremely tiny, almost hard to notice, and I fear my readers will miss them. It would be great if there was a way to specify the icon size (perhaps as simple as "small", "medium", or "large"). Thanks!
