Disentangle and clean the classes of the Audio File Processor (#7069)
## Extract views Extract the classes `AudioFileProcessorWaveView` and `AudioFileProcessorView` into their own files. Reformat the new classes by removing unnecessary whitespace and underscores. Add spaces to if-statements. Cleanup the includes. ## Remove friend relationship Remove the friend relationship between `AudioFileProcessor` and `AudioFileProcessorView`. Introduce getters for entities that the view is interested in.
