Add support for issue topics (a.k.a thematic sections / subsections)

Is your feature request related to a problem? Please describe.
Some journals would like to categorize their articles into thematic groups or collections without having to publish a separate special collection.

Describe the solution you'd like
As an editor, I can configure a set of topics to be linked to my journal. I can also link those topics to specific issues.
As an editor, I can configure a submission field for authors to select the topic their article relates to.
As an author, I can select a combination of article type and topic during submission
As an editor, I can group articles on the published issue page either by article type, topic or a combination of the two.

Additional context
See Harvard Law Review for an example implementation.

Note from users coming from wiley: They would like for each topic to have a description / blurb that can be displayed on the issue page.
