The LyricsWithModels is not needed for NeuralNEtwork, so Baseclass is used for DNN, add padded silicce method. As result:
- LyricsWithModelsBase is used for DNN. LyricsWithModelsCNN._linkTomodels and
- LyricsWithModelsBase._linkTomodels do not make sense.
maybe remove lyrics With models in general.
then reduce if statement in SecionLink.loadSmallAudioFragment()
