/**
* \brief Perform modular inversion of an MPI with respect to a modulus \p N.
*
* \p A and \p X must be associated with the modulus \p N and will therefore
* have the same number of limbs as \p N.
*
* \p X may be aliased to \p A.
*
* \warning Currently only supports prime moduli, but does not check for them.
