Note that all of the enum definitions changed (again?), and now they are
flattened into the 'bindings' namespace. This breaks the API in a way that
is relatively easy to fix, albeit annoying. Attempts to change the enum
generation using default_enum_style() resulted in endless compiler errors.

get_image_page (MagickGetImagePage) is especially useful
for determining the overall dimensions of a GIF, which may have
frames with different widths and heights. In such cases,
get_image_width and get_image_height report the dimensions of
the last frame only.
Using the changes from @gadomski along with some additional work, to get the
generated bindings working again. Works on macOS and FreeBSD 11. A couple of
hacks are needed for FreeBSD, but nothing too serious.
Changed to use the libc prefix, and changed to use the generated enums.
Fixes#22, #15, and #14

The size of the image can vary from version to version (of ImageMagick) and
platform to platform (i.e. MacOS and FreeBSD). As such, allow for a degree
of variability in the resulting image size.

This method goes down to `MagickGetImagesBlob`, which allows for
creating animated gifs.
I didn't abstract out common operations between the two in the interest
of not overly polluting the codebase. However, this new method is almost
identical to `write_image_blob` so you could probably abstract something
out of there.
The test image that was meant to be rotated was generated incorrectly.
It now corresponds to the following ImageMagick command:
$ convert in -rotate 90 -orient left-bottom out
