Add support for pre-processing scale/ops/channel objects
and adding the converted config to the relevant sections.
For ex:
Object.Base.channel."fl" {
shift 0
reg 1
}
Object.Base.channel."fr" {
reg 1
shift 1
}
Will be converted to:
channel {
fl {
reg 1
shift 0
}
fr {
reg 1
shift 1
}
}
And added to the SectionControlMixer that this object belongs to.
