[bug#56803] [PATCH 6/6] gnu: Add hydrus-network.

[Tomasz Jeneralczyk <tj@schwi.pl>]

Hydrus-network has a weekly release cycle and is meant to be used from its own
directory so I artificially spread it out to comply with guix's expectations.

Three binaries from inputs are copied into a directory hydrus knows about:
  * ffmpeg - works as expected
  * swftools - does not do anything neither on guix or Arch linux - possibly
  an unfinished feature, but I left it in, in case it gets fixed in a future version.
  * miniupnpc - times out on my system, but it should work otherwise.

I was not able to build the program's help files. Updating
python-pymdown-extensions to its latest version might be the solution, but
this would require also packaging its new build system that is not present in
guix yet. I decided to cut short there.

Also adds copyright and new used modules.

* gnu/packages/image-viewers.scm (hydrus-network): Add variable.
