An encoder/decoder to/from dense files.

A file format simpler and denser than MNIST, a dense file is binary file of sequential training examples and nothing else (example->label->example->label->etc.).

#### MNIST Testing data

Format | Size | Size on disk

--- | --- | ---

MNIST | 7,850,024 | 7,856,128

Dense | 7,850,000 | 7,852,032

#### Example

```rust

use ndarray::{Array2,array};

let data: Array2 = array![[0, 0], [1, 0], [0, 1], [1, 1]];

let labels: Array2 = array![[0], [1], [1], [0]];

dense::write("dense_reader",&data,&labels).unwrap();

let (read_data,read_labels) = dense::read::("dense_reader",2).unwrap();

assert_eq!(read_data,data);

assert_eq!(read_labels,labels);

```
