Still broken for systems with more states. :(

Current CI runs, specifically the ones without Slycot still fail.

evalfr() returns nan when the non-slycot branch in StateSpace.horner() tries to solve some matrix equations, which are not singular, but probably not conditioned well enough for the underlying LAPACK library.

I cannot reproduce locally. It only fails on the conda based Github Actions CI, which uses MKL.
