Two affiliations for one author

Seems to work already as in: https://preprints.inggrid.org/repository/view/20/

Request:

Add example on how to do it in https://git.rwth-aachen.de/inggrid/template/-/blob/master/metadata/authors.tex

Problem:

affiliation = {WZL,IPT} results in empty affiliation

affiliation = WZL, affiliation = IPT, results in only the second one being listed.
