Support for the determinant with Sparse LU

Currently, It should be straightforward to compute the determinant of a sparse matrix using the decomposition returned by the SparseLU module.
An implementation is available in the attached patch.
However, this determinant can easily overflow. Equilibrate the matrix before the factorization can fix the issue.
This is useful as well to limit the amount of pivoting. So we should add this functionnality before pushing the support to compute the determinant.
