Does not support passing props to Popper component

[liampcollins]

Hi, I've a use case where I need to pass a prop to the Popper component. Could we update the library to support this, perhaps using something like getPopperProps in the same way that getInfiniteLoaderProps is implemented? Happy to do the PR if you think its a change worth making.

Thanks

@liampcollins That sounds good and a PR is most welcome. I haven't had much time for the project lately and hoping someone gets the v4 support finished.

Hi @techniq , I've submitted a PR for this. Whenever you get a chance could you take a look please? Thanks
