[Optional] Persist InMemoryStore blob using FolderStore

[dehann]

hi guys, maybe I am misunderstanding the Slack conversation, but before you start building a new persistence method for InMemStore:

• i'd really like to understand why FolderStore cannot be used as the persistence layer for blobs in InMemStore? Similarly,
• InMemStore can be the cache layer for content from any persisted blob store, including FolderStore.

Firstly, there is no InMemoryStore. It’s not implemented yet and the previous API was moved to the attic. It should be easy to update. implemented in #593

The InMemoryEntries are not only UInt blobs but can be any type and therefore, hard to serialize.

A vector{uint8} FolderBlobStore is implemented. The idea was that more blob formats could be added (possibly layers on UInt8 vectors, although i would like some others)

So to have an inmemorystore for every implemented type in the persisted stores makes sense. Kind of a cache. But not for ‘Any’
