decode_wav_bytes needs a more robust wav head parsing

[sylvainbonnot]

When using recode in streamlitfront apps, the following function choked on some wav files (that could be read with sf.read):

file_to_bytes = Pipe(Path, methodcaller("read_bytes"))
wav_file_to_array = Pipe(
    file_to_bytes,
    decode_wav_bytes,
    itemgetter(0),
    np.array,
    np.transpose,
    itemgetter(0),
)

Link to the app: simple_ml_app_1

We should check the correctness of the function decode_wav_bytes.
