Provide Docker/Podman/apptainer images. #68
Description
It would be nice to have zsync2 as Docker/Podman/apptainer images besides AppImage.
In an HPC environment, there is in general no option to install AppImage.
Singularity/Apptainer (http://apptainer.org/) and Podman (rootless Docker) is for example the only way to run containers on our HPC infrastructure. zsync2 is quite difficult to compile natively on old RedHat versions.
Docker/Podman and SingularityApptainer images are quite easy to make from the Apptainer image.
