Moving optex location at CTAN and TDS

[olsak]

OpTeX location was moved from CTAN:/macros/luatex/optex to CTAN:/macros/optex.
Contributors of OpTeX packages (if any:) should put them to CTAN:/macros/optex-contrib/package.

The location for contributed packages changed! It is now CTAN:/macros/luatex/optex/<package name>. This location is not often needed.

In contrast the location for contributed packages in TeX Directory Structure (the layout distributions like TeX Live use) is TEXMF:/tex/optex/<package name>.
