I am trying to parse a TRE in a NITF following the spec found here (https://nsgreg.nga.mil/doc/view?i=4829&month=10&day=10&year=2019). Specifically, I am having trouble with the BANDSB TRE with the EXISTENCE_MASK field. It is supposed to be an unsigned int that can be used as bit flags for data following after it. I am currently getting garbage at this location from the gdal.getMetadata('TRE') call. Any help would be appreciated.
