TIFF Tag 41728 wrong value expected, file declared not well-formed

This was already mentioned in https://github.com/openpreserve/jhove/issues/767 (closed) but it is not yet fixed in version 1.28.0 (TIFF-HUL 1.9.4).

We process sometimes images with EXIF tag FileSource (41728 / 0xA300) set. Jhove expects the value 7 and declares the file Not well-formed if not found. This is incorrect AFAIK, the specification default is 3 (to indicate a digital camera as source). Other values are also valid indicating a different file sources.
