I2501-01619

This installs Vamb (+ a required PyTorch version from a PR), vclust, and vRhyme for ticket I2501-01619. I have only contributed the last one to EB (https://github.com/easybuilders/easybuild-easyconfigs/pull/22163), as I'm not completely happy with the other two, but just wanted to get it installed. vclust requires some other tools; they are also included in this PR.

Still WIP, as I'm currently trying to build them for all CPUs 🤞
