title: Is it possible to write attribute data to a magick object?
body: <p>I have a few thousand pictures with GPS information included in metadata/exif. However the accuracy of the coordinates is sometimes poor, and I want to update these using data from a more precise GPS. Using the <code>magick</code> package I can access the coordinates, but can't figure out how to edit/write new coordinates.</p>
  
  <pre><code># Taking a random geotagged pic from flickr:   
  library(magick)
  test &lt;- image_read("https://live.staticflickr.com/65535/48568563581_50ea7a9d64_m.jpg?rnd=0.25039150584286607")
  
  # looking at the attributes:
  image_attributes(test)
  
  # Can see that latitude is in:
  image_attributes(test)[22,2]
  
  # But cant edit/change them by, e.g.:*
  
  image_attributes(tessst2)[10,2]&lt;-c("70/1, 14/1, 6655/1000")
