Put blobs in batch

Stores base64-encoded blobs in one request and returns their CIDs in request order. Each blob is stored under its multicodec_code, or 0x55 (raw binary) when none is given. A blob that names a cid must hash to it, or it is refused before it is stored; a urn:cid: prefix is accepted. Blobs are written concurrently, up to the dynamic configuration's blob store write concurrency limit, and a failure does not roll back blobs already written. Requires create_declarations or create_comments in at least one project.
