Base is the base struct for all segment types.

ContiguousHistory is a list of ordered contiguous segments.

Full is a segment that has been added to the store and has been assigned a segment ID.

MetaData adds a PreviousHistorySegmentID, and is the struct that gets serialized into the JSON metadata when a segment is added to the store.

Staged is a segment which has been added to the store and then fetched back again.

Unpublished is a segment that has just been dumped from the database into a zip file but hasn't yet been added to the store so doesn't have any extra metadata.
