The name for 0x70 here is "protobuf":

In the multicodec table the name for 0x70 is defined as "dag-pb":
https://github.com/multiformats/multicodec/blob/master/table.csv#L408

"protobuf" exists in the table but is mapped to 0x50:
https://github.com/multiformats/multicodec/blob/master/table.csv#L30

This is creating an interop issue with /api/v0/block/put?format=dag-pb - it's not understood by go-ipfs.

Can this be fixed?
