  Create an EdDSANamedCurveSpec from the provided curve name. The current implementation fetches the pre-created curve spec from a table.
  
  Parameters:
  
  curveName - the EdDSA named curve.
  
  Returns:
  
  the specification for the named curve.
  
  Throws:
  
  java.security.InvalidAlgorithmParameterException - if the named curve is unknown.
