Impl std::error::Error for error types

[friendlymatthew]

This commit updates the library error types to implement std::error::Error.

Currently, JiterError and JsonError do not implement std::error::Error. This prevents error chaining and interoperability with standard error handling.

use jiter::JsonValue;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let json_data = r#"
        {
            "name": "John Doe",
            "age": 43,
            "phones": [
                "+44 1234567",
                "+44 2345678"
            ]
        }"#;
    let json_value = JsonValue::parse(json_data.as_bytes(), true)?; // <-- can't do this
    println!("{:#?}", json_value);

    Ok(())
}
