Add more features to the BetterNLP library

[neomatrix369]

On the back of this discussion, @shahanesanket and I will take this further
Data-Centric-AI-Community/fg-data-profiling#278, some high-level ideas:

• Missing value analysis
• Text length analysis
  • 2.1 min, max, average, quantiles
  • 2.2 freq words, infrequent words (can include the deepmoji project's tokenizer. it's very robust)
  • 2.2 word cloud. (if it isn't a far stretched goal)

@shahanesanket let's continue with our discussions here.

@shahanesanket any thoughts on the above, shall we get started with your ideas and then draft some code on top of it!

@shahanesanket

Please have a look at this implementation and let me know what you think, it's on the back of the issue you had raised as discussion point on the Pandas Profiling repo:
https://github.com/neomatrix369/awesome-ai-ml-dl/blob/master/examples/better-nlp/notebooks/jupyter/nlp_profiler.ipynb

I'm happy to expound on this further after hearing your response and feedback on it.
