Crate zbitmap 

Pure-Rust LZBITMAP decompression, with no dependencies and no unsafe.

LZBITMAP is the compression format Apple uses for APFS transparent compression (decmpfs types 13 and 14) since macOS 12, including the system’s dyld_shared_cache.

• decompress: decodes a raw LZBITMAP buffer (magic ZBM\x09).
• decmpfs: decodes whole files from their com.apple.decmpfs xattr and resource fork.

The decompressor is a port of libzbitmap by Corellium (MIT).
