fc96aa73f5c7f62452847a31821890ff1f72a5a4 Add a function to extract the secretkey from a keypair (Elichai Turkel)

Pull request description:

  With schnorrsig if you need to tweak the secret key (for BIP32) you must use the keypair API to get compatible secret/public keys which you do by calling `secp256k1_keypair_xonly_tweak_add()`, but after that there's no currently a way to extract the secret key back for storage.
  so I added a `secp256k1_keypair_seckey` function to extract the key
