Basic improvements + optional image support

[Zetaphor]

I love this idea!

Here are some basic improvements:

• Add a requirements.txt to simplify installation
• Move the API URL and key to a separate .env file
• Add a .gitignore for the script outputs and pycache

I've renamed the sanitize function to _format_page to support the changes in #2

This PR additionally implements image support using SearXNG. This does assume you're hosting your own instance or have access to one. The image search works by grabbing the first result matching an images alt tag content.

I've got a lot more ideas about how to improve this. I'm going to continue working in my fork and will later consult you to see if you're interested in what I'm thinking.

I don't use reddit, if you want to reach me on Discord I use the same username there.

Heh, I'm actually working on SD support in my fork. It's very WIP but you can take a look if you're interested.

I'm getting some errors like:
if int(img["width"]) > int(os.getenv("MAX_IMAGE_WIDTH")):
ValueError: invalid literal for int() with base 10: '200px'

any ideas? I just left the url in .env as you had it. Is that the problem?

[Zetaphor]

@scalar27 I've fixed this in my fork in my latest commit.

I've actually decided I'm going to take my fork a very different direction, as it's unclear if/what the future of this repo is intended to be.

I'll leave this PR open if Sebby37 wants to merge it, but I'll be diverging into a new repo that won't be tracking against this one.
