Additional Fat Mach-O Arch Support

[CouleeApps]

Re #1654: Some newer cpu subtypes are not supported yet:

• CPU_SUBTYPE_X86_64_H
• Potentially more, see <mach/machine.h>

Fixed in 2.1.2295-dev. There is a new Universal BinaryViewType. New architecture subtypes should generally be handled now without any required changes as long as the base architecture is available.
