This adds what is effectively an owned wrapper around `Archived<SimpleMetadata>`. Normally, an `Archived<SimpleMetadata>` has to be used behind a pointer (since it has a lifetime attached to its underlying byte buffer), but we create a wrapper around it that owns the underlying buffer and provides free access to the archived type. This in effect creates an anchor point for the archived type and lets us pass it around easily. (There has to be an anchor point for it somewhere.) An alternative to this approach would be to store it as a file backed memory map. But in practice, we're dealing with small files, and just reading them on to the heap is likely to be faster. (Memory maps also have wildly different perf characteristics across platforms.) Note that this commit just defines the type. It isn't actually used anywhere yet.
