Begin adding evaluation scores for all models, initially MUSEDB18 + m…

…odel fix (#169)

* Added initial attempt at script to evaluate model performance using MUSDB18 dataset and evaluation tooling

* Added loading of existing raw scores

* WIP combined scores

* Updated script to process all tracks for all models, and evaluate SDR for all stems supported by MUSDB18. Added combined scores calculated so far.

* Added median score calculation, changed inner/outer loop for tracks vs. model processing, renamed accompaniment

* Fixed UVR-De-Reverb-aufr33-jarredou.pth model by adding new model-data dict appended to the UVR one
