Koa middleware to list or extract archive files based on koa-browse.
npm install --save koa-browse-sevenzip
Koa-browse is required for this middleware to work.
Also a 7z executable is required to be in the app's PATH. If not, it can be
reassigned using the sevenzip module.
const SevenZip = require('sevenzip');
SevenZip.executable = "/home/richard/bin/7z";
