adding hind_encorp dataset
help needed in dummy data extension of the file is .plaintext so dummy data generation is failing
 you can add the `--match_text_file "*.plaintext"` flag when generating the dummy data

also it looks like the PR is empty, is this expected ? yes it is expected because I  made all my changes in  PR  #1186  then I again run code and open PR #1188 to see if this time test passes or not only so there is no code change from #1186 to #1188  
i tried  --match_text_file "*.plaintext" this time it is also not generating dummy data don't know why well this PR includes no code change at all, can you make sure you added your changes in this one ? feel free to ping me when you have added the files so I can take a look and help you with the dummy data how to do that i dont know did i have to open new PR
  actually all my changes are visible in  #1186 but  don't know how to show same changes here these are a the which i did in #1186 and same in #1188

these same codes are in both #1186 and #1188 so because it is already present from PR #1186 because of that it is showing zeor code change in #1188 because it is already present from #1186 how i can show or highlight those changes









 well for me https://github.com/huggingface/datasets/pull/1188/files is blank This PR tries to merge the master branch of you fork into this repo, however I can't find changes with your files inside your master branch.

Maybe you can fork again the repo and try to create another PR ? @lhoestq  i  opened a new pr #1438 but this time it fails many circl ci tests Closing this one since a new PR was created
