Added CUAD dataset
CONTRIBUTOR
1) Changed the language in a few places apart from those you mentioned in README
2) Reduced the size of dummy data folder by removing all other entries except the first
3) Updated YAML tags by using to the past version of `datasets-tagging` app. Will update the quick fix on that repository too in a while
