Reading input cards from simtel files

[nietootein]

Hello pyhessio,

We were wondering if pyhessio supports the reading of the history block from simtel files (-h option in, e.g., read_cta in hessio). We would like to add these infos as metadata to our data files for machine learning, mainly for provenance purposes. Our dumper code makes use of ctapipe & pyhessio.

Ideally, if this feature existed in pyhessio, it would be great if there was a function in ctapipe.io.hessio to retrieve these metadata (e.g. hessio_get_history), but this discussion will come later and will deserve a separate issue in the proper project, I guess...

Cheers,

Daniel

I don't think this is supported yet, but it would be a very nice addition for the pipeline as well (as well as access to histograms as in #49).

This is partially solved in #64 , which allows you to print them out. However, an interface to fetching them as a string might be useful so we can capture and pass on that info to subsequent output files.
