Added dataset Makhzan
The only CI error comes from 
```
FAILED tests/test_file_utils.py::TempSeedTest::test_tensorflow
```

which is not related to your PR and is fixed on master.

You can ignore it @lhoestq I've made the changes. Please review and merge. 

I have a similar PR https://github.com/huggingface/datasets/pull/1562 for another dataset. I'll incorporate your comment about sorting and reducing dummy dataset size there. The CI raises an error `FAILED tests/test_file_utils.py::TempSeedTest::test_tensorflow` but it's not related to this dataset.
This issue is fixed on master You did all the work ;) thanks

merging since the CI is fixed on master
Need help with the dummy data.
