finetune sample data and script.

Sorry, But When I tried to install a new clean environment, it seems that it has stopped working due to some version difference.
It might be better to wait until the stable version comes out.

- finetune.py gptq finetune sample file.
- jawiki3.csv sample data.(Japanese)
- lora_test.py after finetune, you can use lora with this script.
