Model arch

This version of DTG is trained from scratch with 400M param LLaMA arch. Since it is llama arch. Theoritically it should be able to be used in any LLaMA inference interface.

This repo also provided converted FP16 gguf model and quantized 8bit/6bit gguf models. Basically it is recommended to use llama.cpp or llama-cpp-python to run this model. Which will be very fast.
