workaround for Doxygen/LaTeX broken tables

[jgmbenoit]

This patch provides a workaround for a known broken Doxygen LaTeX tables issue reported (and solved) at doxygen/doxygen#11634.

Meanwhile I have noticed that some tables in the generated latex-pdf are larger the page itself. I guess that this can be resolved with multi-lines entries: unfortunately I not familiar with Doxygen to suggest something here.

Thanks, I have merged it.

But please note that some years ago I switched to handwritten markdown documentation:

• README.md: https://github.com/kimwalisch/primesieve/blob/master/README.md
• C API doc: https://github.com/kimwalisch/primesieve/blob/master/doc/C_API.md
• C++ API doc: https://github.com/kimwalisch/primesieve/blob/master/doc/CPP_API.md

Hence I don't maintain the Doxygen documentation anymore. And for the Linux distros where I maintain primesieve (Fedora and OpenSUSE) I ship these markdown documentation files instead of the Doxygen documentation. I switched from Doxygen to markdown documentation because maintaining the markdown documentation is much less time consuming e.g. with the Doxygen documentation I frequently needed to make updates when a new Doxygen version was released (which often caused minor issues that needed to be fixed).

While my markdown documentation may not be perfect, I have not received any complains about it, so I guess users are overall happy with it.
