Compute the probability density function of the Wishart distribution
Inputs: A p x p matrix W where to find the PDF and the p x p positive definite scale matrix Tau and scalar degrees of freedom parameter df characterizing the inverse Wishart distribution. (For the density to be finite, need df > (p - 1).) If the flag log_y is set, return the log probability density – this helps avoid underflow when the numerical value of the density is very small
Output: y is the probability density of Wishart(Sigma, df) at W.
