Create class/function to enable "vision" for chatbots

[Daethyra]

I wasn't able to find much information on giving vision to GPT-4o via LangChain, but I did find these pages:

• LangChain Discussion Question
  • LangChain-Core package: vision-related functions
• This OpenAI documentation may also be helpful, but expects images to have a URL, so it's not likely the route I'll want to go. I could see it being useful in the event that I finagle images inside a HumanMessage shown in the below screenshot. Documentation
