Class for Limiter Stage Limiter is a single band compressor at the end of the processing chain, commonly used to protect the signal from overloading and distortion. Limiters have multiple controllable parameters: enabled/disabled, linkGroup, attackTime, releaseTime, ratio, threshold, and postGain.

Limiters can be linked in groups across multiple channels. Linked limiters will trigger the same limiting if any of the linked limiters starts compressing.

                boolean enabled, 
                int linkGroup, 
                float attackTime,

                float threshold, 
                float postGain)

Class constructor for Limiter Stage

Parameters
`inUse`	`boolean`: true if MBC stage will be used, false otherwise.
`enabled`	`boolean`: true if MBC stage is enabled/disabled. This can be changed while effect is running
`linkGroup`	`int`: index of group assigned to this Limiter. Only limiters that share the same linkGroup index will react together.
`attackTime`	`float`: Attack Time for limiter compressor in milliseconds (ms)
`releaseTime`	`float`: Release Time for limiter compressor in milliseconds (ms)
`ratio`	`float`: Limiter Compressor ratio (N:1) (input:output)
`threshold`	`float`: Limiter Compressor threshold measured in decibels (dB) from 0 dB Full Scale (dBFS).
`postGain`	`float`: Gain applied to the signal AFTER compression.
