 - Deflated files are corrupt when anonymized from the command line ([#80](https://github.com/blairconrad/dicognito/issues/80))

 - Date/time offset is not always the same for a given seed ([#86](https://github.com/blairconrad/dicognito/issues/86))
+- Anonymizing dataset with StationName but no Modality fails ([#97](https://github.com/blairconrad/dicognito/issues/97))
