title: Save numpy array as TIFF sequence using PIL
body: <p>I have seen an example of loading a TIFF sequence of say a 3D tiff stack or animation. However I cannot figure out how to do the opposite, taking say, a 3D+ numpy array and saving it as a TIFF sequence. Are there are any examples of encoding this? I can read a 2D array using PIL.fromarray. It would be nice if this method had some way of loading a multi-dimensional array but a naive method call will throw an unsupported-type exception.</p>
  
  <p>Presumably if one did write such a sequence they might also want to add some headers to dictate channels, time and so forth. My particular bias is being able to open such images in applications like ImageJ/FIJI or converting from TIFF to other formats. Maybe there are better ways to go about this in the first place.</p>
