Description

Currently opening a terms index requires jumping to the end of the terms index and terms dictionaries to decode some metadata such as sumTtf or file pointers where information for a given field is located. It'd be nicer to have it in a separate file, which would also have the benefit of letting us verify checksums for this part of the content.
