Jack Grigg 872471af17 Fix Poseidon instance definition 
For Orchard, we want a Poseidon instance with a width of 3 field
elements and an output of one field element. The Poseidon instances
defined in the Poseidon paper have their output size equal to their
capacity size; with a capacity of 1 and pallas::Base as the field,
Poseidon-128 has the corresponding security level.

We do deviate from the paper's instance by adding a single partial
round, which makes the circuit easier to implement in Halo 2.
