Function: jubjubSchnorrSign()

function jubjubSchnorrSign<A>(
   rtType, 
   msg, 
   signingKey): JubjubSchnorrSignature;

Produces a Schnorr signature over the JubJub curve.

• rtType / msg: the message as a typed Compact value
• sk: signing key as a JubJub scalar (e.g. as returned by jubjubSampleScalar)

The signature scheme:

• Nonce r sampled uniformly at random
• Announcement R = r·G
• Challenge c = PoseidonHash(R.x, R.y, pk.x, pk.y, msg...)
• Response s = r + c·sk (in the JubJub scalar field)
