Button shows up on print media

[smallstepstoday]

Great library. Worked like a charm from the start. One small issue: the button shows up when the page is printed and the printout has more than one page.

It would be great if one didn't have to manually create CSS rules to exclude the button, and I am not sure how to do it given your use of the inline styles. (If I did, I would produce a PR.)

This is a great idea, and I believe a necessity. Ill see about adding this in asap. Thank you

My best advise on this is to simply add the container class to the print media query

@media print {
    .ScrollUpButton__Container {
        display: none important!;
    }
}

I would very much like this to be the default behavior but im reluctant to add a css file to the package just for this since currently all the default behavior styling is done via JS.
