IMPORTANT: Updates to almost all software

This commit primarily affects the configuration step of Maneage'd projects,
and in particular, updated versions of the many of the software (see
P.S.). So it shouldn't affect your high-level analysis other than the
version bumps of the software you use (and the software's possibly
improve/changed behavior).

The following software (and thus their dependencies) couldn't be updated as
described below:
  - Cryptography: isn't building because it depends on a new
    setuptools-rust package that has problems
    (https://savannah.nongnu.org/bugs/index.php?61731), so it has been
    commented in 'versions.conf'.
  - SecretStorage: because it depends on Cryptography.
  - Keyring: because it depends on SecretStorage.
  - Astroquery: because it depends on Keyring.

This is a "squashed" commit after rebasing a development branch of 60
commits corresponding to a roughly two-month time interval. The following
people contributed to this branch.
  - Boudewijn Roukema added all the R software infrastructure and the R
    packages, as well as greatly helping in fixing many bugs during the
    update.
  - Raul Infante-Sainz helped in testing and debugging the build.
  - Pedram Ashofteh Ardakani found and fixed a bug.
  - Zahra Sharbaf helped in testing and found several bugs.

Below a description of the most noteworthy points is given.

  - Software tarballs: all updated software now have a unified format
    tarball (ustar; if not possible, pax) and unified compression (Lzip) in
    Maneage's software repository in Zenodo
    (https://doi.org/10.5281/zenodo.3883409). For more on this See
    https://savannah.nongnu.org/task/?15699 . This won't affect any extra
    software you would like to add; you can use any format recognized by
    GNU Tar, and all common compression algorithms. This new requirement is
    only for software that get merged to the core Maneage branch.

  - Metastore (and thus libbsd and libmd) moved to highlevel: Metastore
    (and the packages it depends on) is a high-level product that is only
    relevant during the project development (like Emacs!): when the user
    wants the file meta data (like dates) to be unchanged after checking
    out branches. So it should be considered a high-level software, not
    basic. Metastore also usually causes many more headaches and error
    messages, so personally, I have stopped using it! Instead I simply
    merge my branches in a separate clone, then pull the merge commit: in
    this way, the files of my project aren't re-written during the checkout
    phase and therefore their dates are untouched (which can conflict with
    Make's dates on configuration files).

  - The un-official cloned version of Flex (2.6.4-91 until this commit) was
    causing problems in the building of Netpbm, so with this commit, it has
    been moved back to version 2.6.4.

  - Netpbm's official page had version 10.73.38 as the latest stable
    tarball that was just released in late 2021. But I couldn't find our
    previously-used version 10.86.99 anywhere (to see when it was released
    and why we used it! Its at last more than one year old!). So the
    official stable version is being used now.

  - Improved instructions in 'README.md' for building software environment
    in a Docker container (while having project source and output data
    products on the local system; including the usage of the host's
    '/dev/shm' to speed up temporary operations).

  - Until now, the convention in Maneage was to put eight SPACE characters
    before the comment lines within recipes. This was done because by
    default GNU Emacs (also many other editors) show a TAB as eight
    characters. However, in other text editors, online browsers, or even
    the Git diff, a TAB can correspond to a different number of
    characters. In such cases, the Maneage recipes wouldn't look too
    interesting (the comments and the recipe commands would show a
    different indentation!).

    With this commit, all the comment lines in the Makefiles within the
    core Maneage branch have a hash ('#') as their first character and a
    TAB as the second. This allows the comment lines in recipes to have the
    same indentation as code; making the code much more easier to read in a
    general scenario including a 'git diff' (editor agnostic!).

P.S. List of updated software with their old and new versions
