Batsim-4.1.0 docker container increased too much
Batsim-4.1.0 seems to weigh 55 Mo, while Batsim-4.0.0 weighed less than 25 Mo (source: dockerhub).
Something probably went wrong in NUR-Kapack's nix recipes, maybe SimGrid-3.29.0's python binding that is included in the closure while it should not.
@adfaure, can you investigate this? (you recently developed a tool for this purpose ;)
