working serialize Slugs with DirectMask runs
Add fully functional flatten, and MakeFromBuffer functionality
for the DirectMaskSubRunSlug type. The other runs will need to come
later.
Add MakeFromBuffer stubs for all the rest of the subrun types.
This has a single unit test to check basic functionality of
flatten and MakeFromBuffer calls.
