Comment (by mikeschroder):

 Did some testing on this and chatted with @ahockley in terms of finding
 out what profiles we should whitelist.

 Notes:
 - It looks like the data that are most interesting are within the `iptc`
 profile, which includes copyright info, but still excludes the majority of
 'extras' that don't need to be in resized images.
 - We're still stripping "Rights Usage Terms," but I haven't tracked down
 the name of the profile yet.
 - Due to current design, when `multi_resize` is run, we're searching for
 profiles in the original every time an image is resized (to re-add them).
 Thinking we should cache/store that information so that it only needs to
 be retrieved once.
