    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.
