Integrated UrduHack and IndicNLP Resources directly into the module

[VarunGumma]

Integrated UrduHack and indic_nlp_resources directly into the module. This negates the need to install the TensorFlow-based Urdu library which was causing some conflicts. Also, the resources are directly added to this module and we do not need to separately clone it and set the path. This will help in easy installation, and packaging, especially for IT2 HF tokenizer.

Hi @anoopkunchukuttan , as discussed I have opened a PR for the indicnlp version we have been using for IT2 and its tokenizer. This repo integrates UrduHack, indic_nlp_resources and is debloated to support the primary requirements of IT2.Hope this can added directly as another branch to the original repo.
