A pre block streams record stream file can be wrapped in a RecordFileItem block item and then into a Block file, we need to add support in block stream verifier to verify the following when it's a wrap of a record file

• the signature files can prove consensus has reached
• the previous hash in the record file matches the hash of the previous record file
• the record file hash and optionally the metadata hash matches what's in the signature file
