`hyphenex` should be added to the package repository

The package https://ctan.org/pkg/hyphenex contains fixed English hyphenations.

Without the package:

% !TeX program = lualatex
\documentclass{article}
\usepackage{showhyphens}
\begin{document}
antinuclear
\enddocument}

With the package hyphenex, it looks as follows:

% !TeX program = lualatex
\documentclass{article}
\usepackage{showhyphens}
\begin{document}
\input{ushyphex}
antinuclear
\enddocument}

Background information

Note that lualatex is used in this example because of the showhyphens package. showhypens is not required to get the hyphenation patterns to work.
