Offset overflow when executing Dataset.map

### Describe the bug

Hi, I'm trying to use `.map` method to cache multiple random crops from the image to speed up data processing during training, as the image size is too big. 

The map function executes all iterations, and then returns the following error:

```bash
Traceback (most recent call last):

pyarrow.lib.ArrowInvalid: offset overflow while concatenating arrays
```

Here is the minimal code (`/home/datasets/DIV2K_train_HR` is just a folder of images that can be replaced by any appropriate):

### Steps to reproduce the bug

```python
from glob import glob

import torch
from datasets import Dataset, Image
from torchvision.transforms import PILToTensor, RandomCrop

file_paths = glob("/home/datasets/DIV2K_train_HR/*")

to_tensor = PILToTensor()
crop_transf = RandomCrop(size=256)

def prepare_data(example):
    tensor = to_tensor(example["image"].convert("RGB"))
    return {"hr": torch.stack([crop_transf(tensor) for _ in range(25)])}

train_data = Dataset.from_dict({"image": file_paths}).cast_column("image", Image())
train_data = train_data.map(
    prepare_data,
    cache_file_name="/home/datasets/DIV2K_train_HR_crops.tmp",
    desc="Caching multiple random crops of image",
    remove_columns="image",
)
print(train_data[0].keys(), train_data[0]["hr"].shape)
```

### Expected behavior

Cached file is stored at `"/home/datasets/DIV2K_train_HR_crops.tmp"`, output is `dict_keys(['hr']) torch.Size([25, 3, 256, 256])`
