CRAN fedora-clang-devel is going to clang 16

[nealrichardson]

clang-16 is currently an "Additional check" on CRAN, but that will be changing in a couple of weeks. From a "please fix to safely retain your package on CRAN" message I received: "clang 16 is now at rc1 and due for release on March 7: we plan to switch fedora-clang checking after Feb 16."

See also #53 and #63 about previous needs to upgrade clang on this image.

Thanks! We are going to switch to the containers here, hopefully soon: https://r-hub.github.io/containers/

In particular, you can use the rhub/clang16:latest container for clang 16. It is not Fedora, but it is clang 16 and libc++, which are the important parts.

Please let me know if it works for your purposes. Thanks!

Just putting a couple of ❤️ ❤️ ❤️ here because this saved me so much time. Thank you both!

Also coming here to say thanks, as I've been wrestling with Docker images and clang16 all day, and had given up in frustration just before this was added!
