use environment variables for tagging

[Datseris]

Hope I did everything right!

Closes #289

[Datseris]

@JonasIsensee I've noticed that collect_results doesn't do any tagging when saving the dictionary. I guess it's on purpose? Should we add tagging there?

Maybe it is not so helpful per se to know the state of the code for producing the results dictionary. What's more important is to know the state of the code when producing each result...? Then again, it doesn't cost much to just replace wsave with tagsave in

!newfile && wsave(filename, Dict("df" => df))

I suppose it was on purpose. My mental model of the collect_results dataframe was always, that it should be rather state-less. So, data deserves a tag but the analysis doesn't.

(I also always had only light-weight analysis inside the collect_results. I feel that this is not the right place to do computationally heavy stuff.)
