As a user, I want to specify a local audio file (e.g., a WAV file) as input to the decoder utility, so that the program knows which audio stream to analyze.
Acceptance Criteria: The utility can be invoked with a command-line argument pointing to an audio file path, e.g.:
sh-dcdr decode --file /path/to/my_morse_audio.wav
