Judging from the SunPy source code on GitHub, OpenCV is only used for
one function (cv2_filter2d), a faster implementation of scipy's
convolve2d. In setup.cfg it is listed a test and docs dependency only.
To reduce size and breakage, IMO it shouldn't be an input. It seems to
be used only at runtime so it could be installed separately.

The opencv package builds opencv-python (cv2 namespace), as mentioned
in the (inputs) comment, although it doesn't ship with the python-
prefix.
