Actually LIEF's dyld info parser is very basic (only offset and size)

Dyld info contains complex structures to rebase, bind and export symbols.

LIEF should be able to handle these structures deeper as well as modelize rebase and binding as relocation

Parser Dyld Info in depth (binding, rebases, exports)
8e596e1 
Binding and rebase bytes codes are now parsed as well as export info
trie. Through ``RelocationDyld`` we created kind of *virtual* relocation
to modeling relocation process performed by Dyld

API Changes (Python / C++)
  * MachO::RelocationDyld   - Added
  * MachO::RelocationObject - Added
  * MachO::Relocation       - Updated according to previous ones

  * MachO::ExportInfo       - Added
  * MachO::BindingInfo      - Added

  * MachO::DyldInfo::rebase_opcodes    - Added
  * MachO::DyldInfo::bindings          - Added
  * MachO::DyldInfo::bind_opcodes      - Added
  * MachO::DyldInfo::weak_bind_opcodes - Added
  * MachO::DyldInfo::lazy_bind_opcodes - Added
  * MachO::DyldInfo::exports           - Added
  * MachO::DyldInfo::export_trie       - Added

  * MachO::Symbol
    - Tied to MachO::BindingInfo (if any)
    - Tied to MachO::ExportInfo (if any)

  * MachO::Binary::relocations - Added
  * MachO::Binary::has_symbol  - Added
  * MachO::Binary::get_symbol  - Added
