Less dependencies and easier setup

torch and llama-cpp-python removed from dependencies. They will have to be custom installed according to the hardware, see INSTALL

The starting code is now the following. No need to make queues, threads and run the chat loop.

from openvoicechat.tts.tts_piper import Mouth_piper as Mouth
from openvoicechat.llm.llm_gpt import Chatbot_gpt as Chatbot
from openvoicechat.stt.stt_hf import Ear_hf as Ear
from openvoicechat.utils import run_chat
from openvoicechat.llm.prompts import llama_sales

if __name__ == "__main__":
    device = 'cuda'

    print('loading models... ', device)

    ear = Ear(silence_seconds=2, device=device)
    john = Chatbot(sys_prompt=llama_sales)
    mouth = Mouth(device=device)
    mouth.say_text('Good morning!')
    run_chat(mouth, ear, john, verbose=True)
