* Inconisistency on whether q_sqrt is triangular fixed. Problem: * KL divergence calculations only take lower triangle parts of q_sqrt in their calculation (implying a lower triangular parameterisation of covariance) * Conditional calculations perform calculations using the whole of q_sqrt. * The end result is if you forgot to add the triangular transform to the q_sqrt, your forward pass may be the same (if you initialise with a triangular matrix), but your gradients will immediately stop q_sqrt being triangular. Fix: * Conditional calulcations now only take the lower triangle parts of q_sqrt in their calculation
