New Sigillographical data extraction

[tla]

The submitted version of my article on sigillography is now in the u:cloud shared folder (RELEVEN/output/DM sigillography).

Here is my experience with the sigillographic part of WissKI:

• what I can do now: creating a boulloterion, adding label to the boulloterion, adding an external source to the boulloterion, adding an internal boulloterion ID (partly functional), creating a seal collection, adding label to a seal collection, adding seals to the seal collection (at least seal IDs), adding authority to seal collection
• missing elements: inscriptions, physical parameters (e.g. diameter), creation assertion (with dating opportunity), and material (as far as I understand the article all of these concern both a boulloterion and a seal made by the boulloterion
• internal boulloterion ID authority cannot find people
• corrupted data at seal collection authority: sometimes, it shows labels such as "WissKI Entity 4369" (and when I edit the seal collection, WissKI does not allow to save it until this kind of authority is there)
• seemingly, I cannot reach seal entities from the seal collections (I can do that from boulloterions)

I found another issue in the seal collections. When I wanted to create a new seal collection, I was not able to add a single person as an authority because the input "according to (person)" also expected an author list (i.e. it only offered author lists as options)
