Cannot derive secrets for ECDH

[singpolyma]

Need to call EVP_PKEY_CTX_new(EVP_PKEY *pkey, ENGINE *e); with the ec pkey and then EVP_PKEY_derive_init from that ctx then call EVP_PKEY_derive_set_peer and finally EVP_PKEY_derive

Right now there is no way I can see to do any of these four calls with luaossl
