Datasets with Audio feature raise error when loaded from cache due to _resampler parameter
## Describe the bug
As reported by @patrickvonplaten, when loaded from the cache, datasets containing the Audio feature raise TypeError.

## Steps to reproduce the bug
```python
from datasets import load_dataset

# load first time works
ds = load_dataset("patrickvonplaten/librispeech_asr_dummy", "clean") 

# load from cache breaks
ds = load_dataset("patrickvonplaten/librispeech_asr_dummy", "clean") 
```

## Actual results
```
TypeError: __init__() got an unexpected keyword argument '_resampler'
```
