Build artefact: Debian archive

[stephengaito]

Should we regularly build Debian archives for release?

Debian archives provide a single release object which when installed using the apt command on the correct Debian release, will ensure all other applications or libraries required by pdf2htmlEX are automatically installed.

While they only work on the Debian family of distributions, this family is used by a very large number of Linux users.

As we have just recently seen with @pablgonz's reports on issue pdf2htmlEX/pdf2htmlEX#26, the Debian archive is also usable on Windows 10 WSL with no changes. So Debian archives actually have a much broader use than just the immediate Debian family of distributions.
