Contour Sequence should be optional. #67

Hi,

Thank you for this awesome tool!

Contour Sequence is Type 3 (Optional), there's no guarantee it'll be present in a given item in the ROI Contour Sequence. I recently stumbled on AttributeError: 'Dataset' object has no attribute 'ContourSequence' while loading an existing RT Struct contour as a mask.

I think this error should not occur. I managed to fix it and will make a pull request to review my correction.

Best,

Maxence
