Mixed-configuration approximation for multiorbital systems out of equilibrium

Dataset corresponding to the manuscript in [1] and [2]. This new version contains also the converged data ("converged_neq_results") for the nonequilibrium setup and, as such, it only extends the dataset of the previous version (https://doi.org/10.3217/1q2tq-cjv28).
In addition, we modified the title (multiorbital) to match the new version amended by the editors. 

We add the DOI [2] (provided by the journal) where the accepted version of the manuscript will be published.
