silent failure with [cmyk]{color}

[iwelch]

if color is loaded with cmyk, the highlight no longer works.

\documentclass[10pt,extrafontsizes,oneside]{memoir}

\usepackage[cmyk]{xcolor}
\usepackage{soulutf8}

\begin{document}

\hl{hello}.  can you see me?

\end{document}

this is one of the gotchas that take one hours to track down in complex files. it would be great if soul could have xcolor throw an error when it tries to work with cmyk.

PS: I also wish we would place a 'deprecated' message on ctan and into the file at soul.sty. I was about to report this to the author when I accidentally learned that the maintainer had become inactive. thanks for taking this on.

This is a duplicate of issue #1. And this here is the repo for soulutf8, not soul. There has been some tries to find a new maintainer but until now nobody took over.

Hm. After some research I think we took some steps here. But I need to check history.
