Attach a hash to a blob, to be signed. The signature is then attached alongside the blob in the same way the derived keys currently is. Then, a reconstituter can attach the signature to the transaction, BEFORE broadcasting.

interface will still be icepick sol sign but the sign subcommand will be overridden so we can detect the derivation path and algorithm, and pass the algorithm to the signer.
