This will be necessary when we start reading from a split bundle
where the header and the thin-pack data live in different files.
The in-core bundle header will read from a file that has the header,
and will record the path to that file. We would find the name of
the file that hosts the thin-pack data from the header, and we would
take that name as relative to the file we read the header from.
