[Feature request]: Reproducibility

[HealthyPear]

Describe the solution you would like

Not sure if this is yet possible, but from the GUI at least not evident.

In order to make Fermi analyses reproducible (from easyfermi), I think we should allow to export or save everything needed to reproduce an analysis made previously by someone else.

I do not know how fermitools works internally, but I am thinking config files, scripts, anything that one might need to reproduce an analysis with easyfermi or more low-level API.

Ideally it should be possible to save the source code equivalent of an easyfermi analysis in a sub output directory so that the next person can re-do it by loading it with easyfermi or by launching python over a set of python scripts with configuration files.
