[WIP] esyn

Rusty Config File Parser.

Example

```rust use esyn::{Esyn, EsynDe};

fn main() { let config = r#" fn testexample() { let a = Config { name: "hi", map: Map::Down, map2: Map::Any("llll"), map3: Map::Named { a: 1, _color: Color { fg: 32, bg: 12 }, }, invertmouse: false, font: Some("abc"), window: Window { color: Color { fg: 32 }, }, tuple: (1, ("hi"), 2), _optenum: None, };

a.window = Window {
    borderless: true,
    topmost: true,
};
a.window.borderless = false;
a.window.color = Color { bg: 12 };

}

"#; let esyn = esyn::Esyn::new(&config).unwrap();

#[derive(Debug, PartialEq, EsynDe)]
enum Map {
    Any(String),
    Named { a: u8, _color: Color },
    Down,
    Up,
}

#[derive(Debug, PartialEq, EsynDe)]
struct Window {
    borderless: bool,
    topmost: bool,
    color: Color,
}

#[derive(Debug, PartialEq, EsynDe)]
struct Color {
    bg: u8,
    fg: u8,
}

#[derive(Debug, PartialEq, EsynDe)]
struct Config {
    name: String,
    invert_mouse: bool,
    font: Option<String>,
    window: Window,
    _opt_enum: Option<Color>,

    map: Map,
    map2: Map,
    map3: Map,
    _tuple: (u8, String, u32),
}

let list = esyn.get::<Config>("test_example").unwrap();
let a = &list[0];

assert_eq!(a.name, "hi".to_string());
assert_eq!(a.map, Map::Down);
assert_eq!(a.font, Some("abc".to_string()));

assert_eq!(a.window.borderless, false);
assert_eq!(a.window.topmost, true);

dbg!(a);

}

```
