Adding chairs as editors

[alexarje]

I wonder whether it would make sense to add information about the chairs in the editor fields? I guess some have, but not all? It would increase the files more, but would also give a more complete picture of the conference over time.

I think it would be great to do that, looks like we have been including them recently (2015, 2018, 2019, 2020).

With my new edit_bibtex_file.py script, you can do this on the command line with:

python3 edit_bibtex_file.py --add_field --field_key editor --field_value "editors go here" year_goes_here
