List missing content subrecord

[Noggog]

This would be an error where a subrecord for a list counter exists, and it is non zero. But the content subrecord that goes along with it cannot be found

Eg, a KSIZ record with count 4 exists, but no KWDA can be found

How do we know what two subrecords we should be looking for? Either we hardcode all known lists record types in existence, or we drive off Mutagen's source xml definitions so it's automatically generated.
