calc_invsqrt_mat

<p>Calculate matrix inverse square root for a covariance matrix</p>

We implement an
adaptation of Jiang & Zeng's (1995) <https://www.genetics.org/content/140/3/1111> likelihood ratio test for testing
the null hypothesis of pleiotropy against the alternative hypothesis,
two separate quantitative trait loci. The test differs from that in Jiang & Zeng (1995) <https://www.genetics.org/content/140/3/1111>
and that in Tian et al. (2016) <doi:10.1534/genetics.115.183624> in
that our test accommodates multiparental populations.
