[PRQ#41781] Merge Request for spleeter2

kajlao [1] filed a request to merge spleeter2 [2] into spleeter [3]: spleeter2 should replace the current spleeter package and be renamed as such. The spleeter package is simply the old version 1.4.0, the current version of spleeter is 2.3.0, which this package is, so it doesn't make sense to have two packages for the same project. https://github.com/deezer/spleeter/tags [1] https://aur.archlinux.org/account/kajlao/ [2] https://aur.archlinux.org/pkgbase/spleeter2/ [3] https://aur.archlinux.org/pkgbase/spleeter/
