Uncomment this to fix a problem with Sanyo MakerNotes. It's probably best
not to in most cases because it seems to only affect the thumbnail tag
which is duplicated in IFD 1, and fixing the offset could actually cause
problems with other software that expects the broken form.
Also, don't log such detected corruption with EXIF_LOG_CODE_CORRUPT_DATA
as the exif front-end currently aborts when it gets such logs. It might be
better to change that behaviour of the front-end instead.
