Arabic pos dialect
looks like this PR includes changes about many other files than the oens for Araboc POS Dialect

Can you create a another branch and another PR please ? Sorry! I'm not sure how I managed to do that. I'll make a new branch.
A README.md and loading script for the Arabic POS Dialect dataset. The README is missing the sections on personal information, biases, and limitations, as it would probably be better for those to be filled by someone who can read the contents of the dataset and is familiar with Arabic NLP.
