Change-Id: I842998baea1568e1d9d1328e4387d14867bd3bb2

This patch is intended to clear transitive dependencies on openexr <at> 2 and freeimage via imageio, which includes a freeimage plugin. Imageio has around ~100 packages to rebuild.

Freeimage last release was back in 2018, it is unknown to me whether it is still maintained and it may contain known and unpatched vulnerabilities (guix lint -c cve freeimage). OpenEXR 2 was also abandoned in favor of OpenEXR 3.

It seems that Debian has a patch to make freeimage work with OpenEXR 3. I may have a look at this later.

I noticed that imageio made a separate package for freeimage due to license concerns but I thought it would be a good fit for Guix for the reasons aforementioend.

Anyway, freeimage is slowly being deprecated in imageio: https://github.com/imageio/imageio/issues/892
