multvardiv 1.0.13

• The diststudent function now returns NaN, with a warning, if delta1 + delta2 - p/2 <= 0 When \(\delta_1 + \delta_2 - \frac{p}{2} \leq 0\), the Rényi divergence (and, therefore, the Bhattacharyya or Hellinger divergence) cannot be computed using the expression implemented in diststudent.
• Added a NEWS.md file to track changes to the package.
