`ligo-skymap-from-samples` has posterior samples as required argument
ligo-skymap-from-samples seems to currently support loading in skypost pickle objects https://git.ligo.org/lscsoft/ligo.skymap/blob/master/ligo/skymap/tool/ligo_skymap_from_samples.py#L125
However, it seems that the script expects the posterior samples file as a required argument. I was wondering if the option to load skypost objects was a feature that was present for debugging but wasn't removed or if it's meant to be there. If the latter, I'd be happy to volunteer and create a merge request that makes the posterior samples file a conditionally required option.
