Natalia Portillo 12a4d684f5 Add support for various ZIP compression methods
- Implement Deflate64 decompression in zip/deflate64.h and zip/deflate64.c.
- Add ZIP Implode decompression functionality in zip/implode.h and zip/implode.c.
- Introduce ZIP Reduce decompression in zip/reduce.h and zip/reduce.c.
- Implement ZIP Shrink decompression in zip/shrink.h and zip/shrink.c.
- Create a unified ZIP interface in zip/zip.h and zip/zip.c to handle multiple compression methods including PPMd, WavPack, and WinZip JPEG.
- Ensure all new functions adhere to the Aaru Data Preservation Suite licensing and documentation standards.
