Dear Maintainer,

I'm trying to change an EXIF value by doing this:

In [1]: from pgmagick import Image

In [2]: img = Image('2_topright_x.jpg')

In [3]: img.attribute('EXIF:Orientation')
Out[3]: '2'

In [4]: img.attribute('EXIF:Orientation', '1')

In [5]: img.attribute('EXIF:Orientation')
Out[5]: '21'

As you can seen the '1' was attached to the original value instead of overwriting it, resulting in an invalid EXIF tag.
