[mp3butcher]

Description

add Liquidsoap2.0 files
(port syntax 1.4 to 2.0)

Testing Notes

I ran libretime on ubuntu 22.04 and liquidsoap2.0

this pr is just the beginning, just 2 files added it's a clean one...
in order to work under 22.04,it requires changes in

1. this pr
2. (feat(legacy): update deprecated PHP code #2789)
3. libretime/propel (port PHP functions prototypes to PHP 8.x compliant syntax propel1#1) or change legacy /composer.json

}

It will require testing changes against ubuntu 20.4 and debian,that's why i think a testing branch can be wise

Thanks for your work and I hope to have a look through it later today! Please keep the 2 features (PHP updates and Liquidsoap) in separate PRs - this helps with review and understanding changes later on, generating changelogs, etc. If you wish to test both sets of changes combined, you can have your second branch be branched off the first and note that the first PR needs to be merged first.
