Hints: Support 'sound-file' and 'sound-name' hints in makoctl list

[earboxer]

Reference: https://specifications.freedesktop.org/notification-spec/latest/ar01s08.html

Added sound-file and sound-name to the data so they'll appear in makoctl list. Also added a criteria for sound-name.

You can use this config to play the sounds:

# Play a sound file when it exists and on-notify isn't overridden
on-notify=exec mpv --really-quiet "$(makoctl list | jq -r '.data[0][0]."sound-file".data')"


# Ring until you click or tap on it
[sound-name="phone-incoming-call"]
on-notify=exec mpv --really-quiet --loop /usr/share/sounds/freedesktop/stereo/phone-incoming-call.oga
on-button-left=exec pkill -9 -f 'mpv .*phone-incoming-call.oga'
on-touch=exec pkill -9 -f 'mpv .*phone-incoming-call.oga'

# Specify any of the sounds you want to hear
[sound-name="message-new-instant"]
on-notify=exec mpv --really-quiet /usr/share/sounds/freedesktop/stereo/message-new-instant.oga
[sound-name="message-new-email"]
on-notify=exec mpv --really-quiet /usr/share/sounds/freedesktop/stereo/message-new-email.oga

Closes #424

Testing notes:

# sound-file hint
notify-send "Where am I?" -h STRING:sound-file:/usr/share/sounds/freedesktop/stereo/audio-channel-front-right.oga
makoctl list | jq -r '.data[0][0]."sound-file".data'
# sound-name hint
notify-send "Click to silence" -h STRING:sound-name:phone-incoming-call
makoctl list | jq -r '.data[0][0]."sound-name".data'

Should probably add a "suppress-sound" BOOLEAN criteria... not sure how widely used any of these are.

Dino at least sends sound-name:phone-incoming-call, so, for mako users, this could be an alternative to dino/dino#1203 (assuming you're okay with binding the action to dismiss it).

To improve the user-experience, maybe there should be an 'on-dismiss' binding, because I want to kill the sound AND close the notification.

(And probably the actions should work with this... not sure if that would be possible to script. maybe I'm asking too much of mako at this point.)

If we implement "truthy/falsey" string comparisons first as in #471, then it will be easier to specify the config:

[sound-file]
on-notify=exec mpv --really-quiet "$(makoctl list | jq -r '.data[0][0]."sound-file".data')"
[sound-name]
on-notify=exec mpv --really-quiet "/usr/share/sounds/freedesktop/stereo/$(makoctl list | jq -r '.data[0][0]."sound-name".data').oga"

#override specific sound
[sound-name="phone-incoming-call"]
on-notify=exec mpv --really-quiet --loop /usr/share/sounds/freedesktop/stereo/phone-incoming-call.oga
on-button-left=exec pkill -9 -f 'mpv .*phone-incoming-call.oga'
on-button-right=exec pkill -9 -f 'mpv .*phone-incoming-call.oga'
on-button-middle=exec pkill -9 -f 'mpv .*phone-incoming-call.oga'
on-touch=exec pkill -9 -f 'mpv .*phone-incoming-call.oga'

What if we (optionally) depend on libcanberra? This way we could straight up play these sounds without a need for external software. I've literally got a crude prototype sitting on my desk, based on this PR (and rebased to master). This was a really easy change, and I am already having ideas on how to further improve it (e.g. adding config options for sound-theme, suppressing notification sounds based on criteria etc.)

@emersion if you're okay with adding an optional dependency (there's precedent with gdk-pixbuf), this could let mako handle notification sounds all by itself, with no need for external software or exec callbacks.

I'm not convinced mako should have built-in support for sound files.
