Enriches ID3-data (artist and title) based on the filename of all mp3-files in either a specific directory if given via command line arguments. If the parameter is being omitted, the current working directory will be used. The filenames need to be in the format "ARTIST - TITLE.mp3" since " - " is the separator.
Every file will be processed in parallel, processing 30 files at once took less than 300ms in multiple tests.
