Subject: bug#34346: 26.1; Big hang when opening text (racket) files with .art extension (image-mode)

I've never heard of .art image files.

According to
https://en.wikipedia.org/wiki/ART_image_file_format

"ART is a proprietary image file format used mostly by the America
Online (AOL) service"

I doubt many people want to look at such images with Emacs.
Given that .art more often seems to be used for something else that
isn't an image but causes big problems for ImageMagick, it seems like a
good idea to add it to the default value of imagemagick-types-inhibit.
