Title: Fix fourtech roots

Fixes a bug where the options for 'complex' or 'all' roots was not being properly handled. In these cases the roots should be computed via a companion matrix using the Fourier coefficients (which is just implemented by calling `roots`). This code previously existed, but the parsing for these input options was not correct.
