Problem: Doesn't handle Dublin Core (DC) repeating fields correctly

[ross-spencer]

When using Dublin Core in Archivematica with repeating fields it's not clear how they will be resolved in Scope. I believe only one of the fields will be used, but I believe because we're working with a dict type once it is parsed then the actual field that will come out in the display is unpredictable. (Though I'm largely seeing the second or last field value appear in the UI).

And this was generated from the Demo CSV sample transfer with an additional SIP level metadata row. I have attached it below for ease of testing in future.
