XMP tag orientation generated by `exiftool` is not handled

Exiftool generates orientation like this:
`<tiff:Orientation>8</tiff:Orientation>`

Current code:
```python3

transposed_image.info["XML:com.adobe.xmp"] = re.sub(
                    r'tiff:Orientation="([0-9])"',
                    "",
                    transposed_image.info["XML:com.adobe.xmp"],
                )
```

does not handle this situation.
