structuralState information for complexes not available via MINERVA API
The structuralState information for complexes doesn't seem to be available via MINERVA API.
I have a few examples from the PAMP signalling pathway (COVID-19 Disease Map).
The CellDesigner XML contains structural state information for the complexes. However, the json received via MINERVA API doesn't. It just says `"structuralState": null`.
