Signature generation algorithm, with custom context string.

Caller is responsible for allocating sufficient memory for signature, based on the length_* members in this object or the per-scheme compile-time macros OQS_SIG_*_length_*.

@param[in] sig The OQS_SIG object representing the signature scheme. @param[out] signature The signature on the message represented as a byte string. @param[out] signature_len The actual length of the signature. May be smaller than length_signature for some algorithms since some algorithms have variable length signatures. @param[in] message The message to sign represented as a byte string. @param[in] message_len The length of the message to sign. @param[in] ctx_str The context string used for the signature. This value can be set to NULL if a context string is not needed (i.e., for algorithms that do not support context strings or if an empty context string is used). @param[in] ctx_str_len The context string used for the signature. This value can be set to 0 if a context string is not needed (i.e., for algorithms that do not support context strings or if an empty context string is used). @param[in] secret_key The secret key represented as a byte string. @return OQS_SUCCESS or OQS_ERROR
