[sh4lt] Implementation of input and output devices

[nicobou]

This adds support of Sh4lt as Gfx input and output. Sh4lt is a Shmdata fork with several improvements (access through "label", timecode, monitoring, and improved data description API).

The code is mostly a mimic of the already existing Shmdata Gfx Input and Output, but adapted according to the Sh4lt API.

It has been tested with the following GStreamer pipelines:

• gst-launch-1.0 sh4ltsrc label=score_output do-timestamp=true ! videoconvert ! xvimagesink sync=true
• gst-launch-1.0 -v videotestsrc pattern=0 ! video/x-raw, format=ABGR, width=1920, height=1080, framerate=30/1 ! sh4ltsink label=to_score

arf, I don't know why Github does not allow me to run all the CI pipelines on this, investigating..

Wops, got a fair bit of CI pipelines failing.

• looks like time.cpp in sh4lt does not make macOS happy: https://github.com/ossia/score/actions/runs/10209159885/job/28246746961#step:5:1382

oh thanks for the TL;DR

I tried several CI pipelines through docker, it should be better now. Let's see what the CI says now 🤞

[jcelerier]

my computer happened to inadvertently reboot under macOS thus I could try to fix the remaining build failures there : https://gitlab.com/sh4lt/sh4lt/-/merge_requests/34

[jcelerier]

also @aklevy I think we could add the logo to the website when it's merged if you have a bit of time ! https://gitlab.com/uploads/-/system/project/avatar/60555302/Sh4lt-300x300.png
