读取生命游戏的图样文件，返回一个活细胞坐标的 Iterator。

## 支持的格式

- [RLE](https://www.conwaylife.com/wiki/Run_Length_Encoded)
- [Plaintext](https://www.conwaylife.com/wiki/Plaintext)
- [apgcode](https://www.conwaylife.com/wiki/Apgcode)

## 范例

### 从字符串中读取:

```rust
use ca_formats::rle::Rle;

const GLIDER: &str = r"#N Glider
#O Richard K. Guy
#C The smallest, most common, and first discovered spaceship. Diagonal, has period 4 and speed c/4.
#C www.conwaylife.com/wiki/index.php?title=Glider
x = 3, y = 3, rule = B3/S23
bob$2bo$3o!";

let glider = Rle::new(GLIDER).unwrap();
assert_eq!(glider.header_data().unwrap().x, 3);
assert_eq!(glider.header_data().unwrap().y, 3);
assert_eq!(glider.header_data().unwrap().rule, Some(String::from("B3/S23")));

let cells = glider.map(|cell| cell.unwrap().position).collect::<Vec<_>>();
assert_eq!(cells, vec![(1, 0), (2, 1), (0, 2), (1, 2), (2, 2)]);
```

### 从文件中读取:

```rust
use std::fs::File;
use ca_formats::rle::Rle;

let file = File::open("tests/sirrobin.rle").unwrap();
let sirrobin = Rle::new_from_file(file).unwrap();

assert_eq!(sirrobin.count(), 282);
```
