Incorrect Orientation Tag Extraction

Issue Title: Incorrect Orientation Tag Extraction

Description

I am encountering an issue with the exif crate where the orientation tag extracted from an image file appears to be incorrect. Specifically, the image's orientation is reported as "row 0 at right and column 0 at top" even though other tools correctly report the orientation as "Horizontal (normal)".

Steps to Reproduce

Extract the Exif metadata and check the orientation tag by the exif crate.

Verify the correct Exif orientation using other tools like ExifTool or Python's Pillow library.

Using ExifTool:
```
exiftool test_image.jpg
```
Look for the Orientation tag in the output.

Using Python's Pillow Library:

from PIL import Image, ExifTags

image_path = 'test_image.jpg'
image = Image.open(image_path)
exif_data = image._getexif()
if exif_data:
 for tag, value in exif_data.items():
     tag_name = ExifTags.TAGS.get(tag, tag)
     if tag_name == 'Orientation':
         print(f"{tag_name}: {value}")

Compare the orientation tag extracted using the exif crate with the correct orientation from the other tools.

Expected Behavior

The orientation tag should be reported as "Horizontal (normal)" (Exif value 1).

Actual Behavior

The orientation tag is incorrectly reported as "row 0 at right and column 0 at top".

Code Sample

Here is a code snippet used to extract the Exif metadata:

use std::{io, path::Path};

pub fn process_image_info(source_path: &Path) {
    let exif = read_exif(&source_path);
    for field in exif.fields() {
        let tag = field.tag.to_string();
        let value = field.display_value().with_unit(&exif).to_string();
        println!("(tag, value) is {:?}", (tag.clone(), value.clone()));
    }
}

fn read_exif(file_path: &Path) -> exif::Exif {
    let exif_reader = exif::Reader::new();
    let file = std::fs::File::open(file_path).unwrap();
    let mut bufreader = io::BufReader::with_capacity(1024 * 1024, &file);
    let exif = exif_reader.read_from_container(&mut bufreader).unwrap();
    exif
}

Comparison with Other Tools

When extracting the same Exif data using other tools like ExifTool or Python's Pillow library, the orientation is reported as "Horizontal (normal)" (Exif value 1).
