CMCE key generation specification

Encapsulates the choice of Classic McEliece parameter set (variant) to be used when generating new key pairs. Each variant corresponds to a standardized security level and key size trade-off as defined in the post-quantum KEM standardization process.

Usage example:

 // Generate a key pair for McEliece 8192128F (256-bit security, fast)
 CmceKeyGenSpec spec = CmceKeyGenSpec.mceliece8192128f();
 KeyPair kp = alg.asymmetricKeyBuilder(CmceKeyGenSpec.class).generateKeyPair(spec);

1.0
