 'cwe': ['CWE-787'], 'message': 'fix use_full_image==false case (#365)

Some fixes to the case where the full modular image is skipped:

- don't assume that everything happens at the modular AC group level (minShift==0), there can also be upsampling causing channels to have nonzero shift even when there's no Squeeze
- for partial decodes (when zerofill is true), don't try to fill the full image when it's not used. Instead initialize the decoded image with zeroes and skip the decoding.'
