[bug#55510] [PATCH] gnu: qpwgraph: Add qpwgraph.

[J. Sims]

Hello,

This patch adds the qpwgraph application, which is a visual interface to
PipeWire connections. Besides managing connections and just being
neat, it can also serve to easily check that a PipeWire configuration
is setup and working (the purpose for which I packaged it). Hopefully,
others will find it useful as well.

Note that I put it in gnu/packages/audio.scm because that made the most
sense to me after a quick check of the packages files. If there's a
better one, I can redo the patch with it in that file.

Thanks,
Juli
