Detailed Description
Class that represents the LC_DYLD_CHAINED_FIXUPS command.
This command aims at providing rebase and binding information like the DyldInfo's bytecode. Compared to the DyldInfo bytecode, these chained fixups are taking less space.

The compression algorithm (if any) used to store the symbols 0 means uncompressed while 1 means zlib compressed.
As far of the version v852.2 of dyld loader, it only supports uncompressed format
