Import of IMS Giotto mammography RDSR fails

[Ed McDonagh]

Appears to not have a content sequence describing the label type for an irradiation event content label.

Relevant code here: https://bitbucket.org/openrem/openrem/src/da0dfc2c53f0817de2e8cd48382e6d98266514bd/openrem/remapp/extractors/rdsr_methods.py#lines-780

Issue reported by Marco Ovidi in the google group

Probably requires a try: except: around the attempt to get the ContentSequence. I’m hoping to see an example to see what is in the Irradiation Event Label which hopefully will indicate whether not having a Label Type ContentSequence is valid or not.

Either way it should work.
