v3.1.1

We've completely refactored almost the entire codebase (over 55 files), to improve overall modularity and simplification of structure to ensure less bugs, and more easy development. In addition, we've finally added image support (!!!). We've also improve the GPT Researcher PIP package which can now return source results, scraped images, research report sections and more! Lastly, thanks to the amazing community you can check out below much more improvements. Thank you to everyone! 

## Updated Demo with images

## New PIP functions
```python
from gpt_researcher import GPTResearcher
import asyncio

async def get_report(query: str, report_type: str):
    researcher = GPTResearcher(query, report_type)
    research_result = await researcher.conduct_research()
    report = await researcher.write_report()
    
    # Get additional information
    research_context = researcher.get_research_context()
    research_costs = researcher.get_costs()
    research_images = researcher.get_research_images()
    research_sources = researcher.get_research_sources()
    
    return report, research_context, research_costs, research_images, research_sources

if __name__ == "__main__":
    query = "what team may win the NBA finals?"
    report_type = "research_report"

    report, context, costs, images, sources = asyncio.run(get_report(query, report_type))
```
