Hey there!, In this pull request I have made this following contributions :

• Python Module to run queries : I have added a module named LocalQueryRunner. This module contains a class named RunLocalQuey. This class have a method named get_response that takes a prompt parameter and returns the response from LLM. A user can use this module in a separate python file by using this spinnet :-

      from LocalQueryRunner.querylocal import RunLocalQuey
  
      runner = RunLocalQuey()
      while True:
          user_input = input("<user> ")
          response = runner.get_response(prompt=user_input)
          print(f"\n<model> {response}")

• Updated the docs according to the modifications I made : As per the modifications I made I also updated the instruction for a user to run queries locally.
