JSON's produced of DICOM header are invalid

[kmader]

The JSON files produced when including the dicom header are invalid due to a bug in the json library see https://www.na-mic.org/Bug/view.php?id=4342

import json
from dicom.tag import TupleTag
out_json_str = json.dumps(TupleTag((123,456))) # '(007b, 01c8)'
json.loads(out_json_str) # ValueError: No JSON object could be decoded

fixed by making a new 'robust' read function which automatically removes these lines
