研究方向
First, study the CR3 specification linked in the issue (https://github.com/lclevy/canon cr3). Then, examine the existing codebase for how other raw formats (e.g., CR2) are supported in the library, specifically looking at classes like 'JpegMetadataReader' or 'ExifReader'. The implementation would likely involve a new reader class and integration into the existing metadata extraction pipeline. The sample files provided can be used for testing. There are 8 comments in the issue that may contain additional context.
