EXIFTool can detect when the offset of tags is incorrect

[ExifTool] Warning : [minor] Possibly incorrect maker notes offsets (fix by 1060?)

Can we detect incorrect offsets with metadata-extractor and ideally fix them in the same way?

研究方向
Investigate how EXIFTool detects incorrect maker notes offsets, as referenced in the StackOverflow link. Explore the metadata extractor codebase to understand current maker notes parsing, focusing on ExifReader and MakerNotesDirectory classes. Determine if a similar offset fix (e.g., adjusting by 1060) can be applied. Review the linked SO thread for additional context and ensure the fix integrates cleanly with the library's existing architecture.
