Looking for reviews on GOFF writer

Hi!

Sorry if this is not the right category.

I need some help with review on the first part of the GOFF writer (⚙ D111437 [SystemZ/z/OS] Implement GOFF writer for empty files). It adds a new MC writer for the GOFF object file format used by z/OS. As first patch, it only writes the structure of the GOFF file without content. The focus is more if it fits correctly into the MC structure.
Thanks!

Regards,
Kai
