How to receive further information of publication ("journal" and "issue")

[ewolf47]

@AndyDaniel1 In the course of Issue #3341, we noticed that the approach we implemented in Issue #3249 unfortunately does not work reliably. It was about getting information about the journal and issue. In #3249 we tried to request this information via poi.org. As it turned out, this approach is unfortunately not stable, as poi.org forwards the requests. Unfortunately, the responses to the requests are not uniform JSONs. This means that we have to find another way to get the information. Is it possible to add two columns in the import Excel file that hold the information about "journal" and "issue"?
Or do you have a different approach?

FYI: as you can see in #3341, in the production system we removed the request to poi.org for the time beeing.

@ewolf47 I will discuss this with @henrikeschmidtchen, who is responsible for the related publication database. However, as other issues are more urgent, we will postpone this issue for the time being.
