Release v0.0.9

New Error handling procedures on verification. The return of the verify and unpackAndVerify methods now return an object with:

{ 
  status: one of the error codes below. 
  contents: the body of the JWS, which is also the same object the user passed to the sign function. 
  issuer: issuer 
  raw: the JWS raw content (headerRaw, body, signature)
}

New ERROR codes for the status field

const INVALID_COMPRESSION = "invalid_compression";      // could not decompress the byte array
const INVALID_SIGNING_FORMAT = "invalid_signing_format";// invalid COSE, JOSE, W3C VC Payload
const KID_NOT_INCLUDED = "kid_not_included";            // unable to resolve the issuer ID
const ISSUER_NOT_TRUSTED = "issuer_not_trusted";        // issuer is not found in the registry
const TERMINATED_KEYS = "terminated_keys";              // issuer was terminated by the registry
const EXPIRED_KEYS = "expired_keys";                    // keys expired
const REVOKED_KEYS = "revoked_keys";                    // keys were revoked by the issuer
const INVALID_SIGNATURE = "invalid_signature";          // signature doesn't match
