[bug#42180] [PATCH 00/22] Add extracting download, importer for hex.pm and rebar3 build-system for Erlang

[Hartmut Goebel <h.goebel@crazy-compilers.com>]

This adds

* "extracting download", which is meant to be used for package repositories
  where the actual source archive is packed into another archive, eventually
  carrying meta-data.  Using this derivation saves both storing the outer
  archive and extracting the actual one at build time.  The hash is calculated
  on the actual archive to ease validating the stored file.

  This currently is used be the hex.pm impoter (see below). But I've been
  told, this could be usefull for ruby, too.

* importer for hex.pm, a repository for Erlang and Elixir

* rebar3 build-system for Erlang

* Required modules
