why the stratify option is omitted from test_train_split function?
Hi ! It's simply not added yet :)

If someone wants to contribute to add the `stratify` parameter I'd be happy to give some pointers.

In the meantime, I guess you can use `sklearn` or other tools to do a stratified train/test split over the **indices** of your dataset and then do
```
train_dataset = dataset.select(train_indices)
test_dataset = dataset.select(test_indices)
```
why the stratify option is omitted from test_train_split function?

is there any other way implement the stratify option while splitting the dataset? as it is important point to be considered while splitting the dataset.
