描述

Metadata-extractor can't read the EXIF and GPS tags from the referenced HEIC file. It is made with an iPhone 13 Pro with the latest iOS version and it has been edited with the iPhone Photo App.

(We have been testing with v2.15 of Metadata-extractor.)

研究方向
Start by examining the existing HEIC metadata reader class (e.g., HeicReader.java) in the metadata extractor source code. Identify where EXIF and GPS tags are expected to be extracted. Compare the parsing logic with the provided sample HEIC file (IMG 8780.HEIC) to see where it fails. Look at comments in the issue for any hints or partial solutions. Test with a known working tool like exiftool to verify expected metadata. Implement necessary changes to handle the EXIF and GPS tags correctly.
