amadeus: Add missing compressor effect from REV11 (#4010)1.1.435
* amadeus: Add missing compressor effect from REV11
This was in my reversing notes but seems I completely forgot to
implement it
Also took the opportunity to simplify the Limiter effect a bit.
* Remove some outdated comment
* Address gdkchan's comments
