[wannaphong]

from #468, I port PerceptronTagger class to PyThaiNLP.

• A Good Part-of-Speech Tagger in about 200 Lines of Python https://explosion.ai/blog/part-of-speech-pos-tagger-in-python
• Source code for nltk.tag.perceptron https://www.nltk.org/_modules/nltk/tag/perceptron.html

Train model: https://colab.research.google.com/drive/1iz4aRLBmyA_q9CY5P4zHmPG_v5iOaWgH?usp=sharing
