This adds support for all the MachO *_command structures. The load_command payloads still are not represented, but that will come next.

This patch adds basic support for MachO::load_command. Load command types and sizes are encoded in the YAML and expanded back into MachO.
The YAML doesn't yet support load command structs, that is coming next. In the meantime as a temporary measure when writing MachO files the load commands are padded with zeros so that the generated binary is valid.

I've added the reserved field as an "optional" in YAML, but I've added asserts in the yaml2macho code to enforce that the field is present in mach_header_64, but not in mach_header.

With this change obj2yaml and yaml2obj can now round-trip mach_headers.
This change also adds ObjectYAML/MachO tests.

Adding the initial files for adding MachO support to yaml2obj. Passing a MachO file will result in an error.
I will be implementing obj2yaml and yaml2obj for MachO in parallel so that one can be used to test the other.
