Add another datatype to check if it's easy to add another datatype (#4)

# Objective

This PR adds a new datatype for **BBox** to ensure that everything work
well and it's easy to add a new datatype.

# Datatypes & Usage

- [x] Image

```Rust
use crate::image::Image;

let flat_image = (0..27).collect::<Vec<u8>>();
let image = Image::new_rgb8(flat_image, 3, 3, Some("camera.test")).unwrap();

let final_image = image.into_bgr8().unwrap();
let final_image_data = final_image.data.as_u8().unwrap();

let expected_image = vec![
    2, 1, 0, 5, 4, 3, 8, 7, 6, 11, 10, 9, 14, 13, 12, 17, 16, 15, 20, 19, 18, 23, 22, 21,
    26, 25, 24,
];

assert_eq!(&expected_image, final_image_data);

use crate::image::Image;

let flat_image = vec![0; 27];
let original_buffer_address = flat_image.as_ptr();

let bgr8_image = Image::new_bgr8(flat_image, 3, 3, None).unwrap();
let image_buffer_address = bgr8_image.as_ptr();

let arrow_image = bgr8_image.into_arrow().unwrap();

let new_image = Image::from_arrow(arrow_image).unwrap();
let final_image_buffer = new_image.as_ptr();

assert_eq!(original_buffer_address, image_buffer_address);
assert_eq!(image_buffer_address, final_image_buffer);
```

- [x] BBox

```Rust
use crate::bbox::BBox;

let flat_bbox = vec![1.0, 1.0, 2.0, 2.0];
let confidence = vec![0.98];
let label = vec!["cat".to_string()];

let bbox = BBox::new_xyxy(flat_bbox, confidence, label).unwrap();
let final_bbox = bbox.into_xywh().unwrap();
let final_bbox_data = final_bbox.data;

let expected_bbox = vec![1.0, 1.0, 1.0, 1.0];

assert_eq!(expected_bbox, final_bbox_data);

use crate::bbox::BBox;

let flat_bbox = vec![1.0, 1.0, 2.0, 2.0];
let original_buffer_address = flat_bbox.as_ptr();

let confidence = vec![0.98];
let label = vec!["cat".to_string()];

let xyxy_bbox = BBox::new_xyxy(flat_bbox, confidence, label).unwrap();
let bbox_buffer_address = xyxy_bbox.data.as_ptr();

let arrow_bbox = xyxy_bbox.into_arrow().unwrap();

let new_bbox = BBox::from_arrow(arrow_bbox).unwrap();
let final_bbox_buffer = new_bbox.data.as_ptr();

assert_eq!(original_buffer_address, bbox_buffer_address);
assert_eq!(bbox_buffer_address, final_bbox_buffer);
```

# Quick Fixes

- I also improved readability and consistency with Rust formatting,
following the guidelines mentioned in [this
comment](#1 (comment)).
- Fix Arrow Array extraction from Union inside #3 
- Fix Dora compatibility (by viewing objects when it's not possible to
own them) inside #5
- I improved the structure of the library, with separated packages and
with some `features` as one might want to use `fastformat` only with
ndarray/arrow. #6
