ARROW-7595: [R][CI] R appveyor job fails due to pacman compression change Well, that's an afternoon of my life I won't get back. The cause seems to be https://www.archlinux.org/news/now-using-zstandard-instead-of-xz-for-package-compression/, which broke some (very reasonable) assumptions about what files were being generated and how they were compressed. Closes #6215 from nealrichardson/appveyor-debug and squashes the following commits: b2a310078 <Neal Richardson> export PKGEXT f262c5f4f <Neal Richardson> Cleanup 901a76fde <Neal Richardson> Embrace zstd 5abac5536 <Neal Richardson> Try to figure out why we're getting .zst files instead of .xz 2f461f73f <Neal Richardson> ls a07d3368c <Neal Richardson> Revert this shell change f0ffd3087 <Neal Richardson> try a couple things 8336f0280 <Neal Richardson> Test different VS images Authored-by: Neal Richardson <neal.p.richardson@gmail.com> Signed-off-by: Neal Richardson <neal.p.richardson@gmail.com>
