`xz-utils` required for installation

[bart1]

I noticed installation failed in the docker container rocker/tidyverse see below. This is resolved when xz-utils are installed. It might be good to add this to the system requirements or atleast improve the error message

(base) ...@...:~$ docker run rocker/tidyverse /bin/bash -c 'apt-get update; apt-get install -yy  cargo; R -e "remotes::install_cran(\"gifski\")"'

Thanks. Using xz is the official R policy on Rust packages, so I think it should be part of the default R installation and we may assume it in packages. But maybe the rocker folks think different. https://cran.r-project.org/web/packages/using_rust.html

[bart1]

Do you think this should then be brought up in the rocker repository for a general solution?

[jeroen]

Yes I think so. I don't think it makes sense for R packages to test for the presence of standard tooling that is assumed by R.
