+/** Create Silent Payment output public key (both for sender and receiver).
+ *
+ *  Given a shared_secret, a recipient's spend public key B_spend, an output
+ *  counter k, and an optional label_tweak, calculate the corresponding
+ *  output public key:
+ *
+ *  B_m = B_spend + label_tweak * G
+ *  (if no label tweak is used, then B_m = B_spend)
+ *  P_output = B_m + hash(shared_secret || ser_32(k)) * G
+ *
+ *  Returns: 1 if outputs creation was successful. 0 if an error occured.
+ *  Args:                  ctx: pointer to a context object
+ *  Out:   output_xonly_pubkey: pointer to the resulting output x-only pubkey
+ *  In:        shared_secret33: shared secret, derived from either sender's
