Get an icon resource as {channel: array}. Note that
the arrays are bottom-up like windows bitmaps and will likely
need to be flipped or transposed in some way.

IcnsImageFilea!
PIL image support for Mac OS .icns files.
Chooses the best resolution, but will possibly load
a different size image if you mutate the size attribute
before calling 'load'.
The info dictionary has a key 'sizes' that is a list
of sizes that the icns file has.

Saves the image as a series of PNG files,
that are then combined into a .icns file.
