[ELPA] New package: listen

[Adam Porter]

Hi,

I'd like to submit a new package to ELPA, named "Listen".  It's a simple 
audio/music player that uses VLC as a backend.

https://github.com/alphapapa/listen.el

Compared to other Emacs music players like EMMS, Bongo, etc, it's much 
simpler to use: no setup or configuration is required--just "M-x listen 
RET" and use the Transient menu to begin.

Compared to packages that use MPD as a backend, Listen provides a 
simpler UI, and it doesn't require installing and configuring MPD; the 
user just selects one or more files to play.  (However, support is 
provided for discovering and playing tracks from a local MPD library by 
searching its metadata database.)

It's extensible, so e.g. a new backend could easily be added to use 
something like MPV to play files.

A queue (playlist) view is provided using the nice new Vtable library in 
Emacs 29.  And a library view is provided using the Taxy and 
Magit-Section libraries to browse tracks grouped by metadata.

For more details (though there's not much else to say), please see the 
readme/Info manual.

By the way, unlike with some other packages I've submitted, I've not 
fully settled on the name, so I'm open to suggestions.  I considered 
naming it "EMP" (for "Emacs Music Player", which is fun and concise, and 
which is surprisingly not yet taken--although Nic Vollmer has an 
unpackaged library by that name, but he's graciously offered me the name 
for use with this package).  But "Listen" seemed more descriptive and 
concise enough, so that's what I've gone with for now.

Thanks,
Adam
