ARM audio support broken

### Describe the bug

`datasets` 4.0 moved to using `torchcodec` for audio datasets, which doesn't support ARM hardware under Linux and Windows

### Steps to reproduce the bug

try:
* Try to install `torchcodec` under Linux ARM64

or:
* Try to install `torchcodec` under Windows ARM64

or, on either of those platforms, using datasets >= 4.0:
* `dataset = load_dataset("garak-llm/audio_achilles_heel")`

### Expected behavior

dataset will load as expected

### Environment info

ARM environment

Python 3.13+

`datasets>=4.0`

Using `torchaudio`
