Create Mach-O parser

MacOS binary executable format.

Required functionality should be to at least retrieve all the "basic" information from an Mach-O (e.g. imports, exports, metadata, sections...) but also code signing information.

Ideally we'd also be able to use it to create pystandalone binaries (for which we currently depend on LIEF).
