dfWishart

This uses simulations to match the rse

Provides the random number generation (in parallel) needed for
'rxode2' (Wang, Hallow and James (2016) <doi:10.1002/psp4.12052>) and 'nlmixr2'
(Fidler et al (2019) <doi:10.1002/psp4.12445>).
This split will reduce computational burden of recompiling 'rxode2'.

<dt>rse</dt>
<dd>This is the rse that we try to match, if not specified,

<dt>upper</dt>
<dd>The upper boundary for root finding in terms of
degrees of freedom. If not specified, it is n*200</dd>
<dt>totN</dt>
<dd>This represents the total number of simulated inverse

<dt>diag</dt>
<dd>When <code>TRUE</code>, represents the rse to match is the
