Module providing adding following load commands:

• LC_LOAD_DYLIB
• LC_LOAD_WEAK_DYLIB
• LC_RPATH

Adding loads can be accomplished with keeping the old signature or removal of it. Module will check whether there is enough space for the new load and return ErrNotEnoughSpace if there is not enough.

This module is heavily inspired/guided by insert_dylib, install_name_tool projects.

It supports 32bit and 64bit architectures with assumed little endian. FAT binaries are not yet supported.
