当shard/raw list中存在多通道数据，dataset会在padding部分报错，错误信息如下(or 类似)

    padded_wavs = pad_sequence(sorted_wavs, batch_first=True, padding_value=0)
  File "/opt/conda/lib/python3.10/site-packages/torch/nn/utils/rnn.py", line 399, in pad_sequence
    return torch._C._nn.pad_sequence(sequences, batch_first, padding_value)
RuntimeError: The size of tensor a (2) must match the size of tensor b (26645) at non-singleton dimension 1

This pr tries to fix the above problem
