Function schnorrSignWithAuxRand

schnorrSignWithAuxRand(
    ecdsaPrivateKey: Uint8Array,
    message: Uint8Array,
    auxRand: Uint8Array,
): Uint8Array
Sign a message using Schnorr signature with specific auxiliary randomness. This is useful for deterministic signing in tests.
Parameters
- ecdsaPrivateKey: Uint8Array
  32-byte private key
- message: Uint8Array
  Message to sign
- auxRand: Uint8Array
  32-byte auxiliary randomness (per BIP-340)
Returns Uint8Array
64-byte Schnorr signature
