Make same changes as in fuzzyjoin to adapt to tidyr v1.0.0

[jennybc]

We are working towards a release of tidyr v1.0.0. tidyr::nest_() has been deprecated for a while and will become defunct in this release. This PR makes the same changes made in fuzzyjoin (dgrtwo/fuzzyjoin@a39fc46) to modify these calls. This code works with CRAN and dev tidyr.

tidygenomics will fail R CMD check until fuzzyjoin releases on CRAN, since there are calls to fuzzyjoin::genome_join() in the intro vignette. So it would make sense to submit to CRAN after fuzzyjoin but before tidyr.

I merged your changes, thank you very much Jenny for making the pull request.

I am not quite sure why do you think that R CMD check will fail. Is the interface of fuzzyjoin::genome_join() going to change? If it just that the internal calls of nest_() are replaced there shouldn't be any problems, right?

Yeah, you're right. Your vignette would start failing if tidyr submits before fuzzyjoin. But hopefully the order will be the other way around.

And, to be clear, this implies that you can submit an update to CRAN at your earliest convenience.

Great. Yes, I will try and see that I push an update to CRAN in the coming days :)
