gemini-rs 0.3.2

# STILL A WIP

A library to use Google Gemini's API directly in Rust!
Made because the current options weren't very capable and didn't support 100% of the official API.

# Example

```rs
// main.rs
use gemini_rs::Conversation;

#[tokio::main]

async fn main() {
    let mut convo = Conversation::new(
        std::env::var("GEMINI_API_KEY").unwrap(), // Replace with however you want to get your API key
        "gemini-1.5-flash".to_string() // Replace with the desired model from https://ai.google.dev/gemini-api/docs/models/gemini
    );

    let a = convo.prompt("If you had to describe Risk of Rain 2 in one word, what word would it be?").await;
    println!("{a}");
    let b = convo.prompt("Now explain your reasoning").await;
    println!("{b}");
}
```

# Roadmap

- [x] Error handling
- [x] Conversation history
- [x] Useless refactor for no good reason (*cry for help*) (x2)
- [ ] Make more operations for conversations (saving, loading, etc.)
- [ ] Image support
