This allows reading the metadata contained in tar-split without expensively recreating the whole tar stream including full contents. We have two use cases for this: - In a situation where tar-split is distributed along with a separate metadata stream, ensuring that the two are exactly consistent - Reading the tar headers allows making a ~cheap check of consistency of on-disk layers, just checking that the files exist in expected sizes, without reading the full contents. This can be implemented outside of this repo, but it's not ideal: - The function necessarily hard-codes some assumptions about how tar-split determines the boundaries of SegmentType/FileType entries (or, indeed, whether it uses FileType entries at all). That's best maintained directly beside the code that creates this. - The ExpectedPadding() value is not currently exported, so the consumer would have to heuristically guess where the padding ends.
