Replacement of the FXRack with MixingConsole

This commit include all the audio fixes and modification
- FXEngine support computation on float32_t instead of intergers only
- Migration of the PlateReverb to the FXElement structure
- Fixing shimmer to be stereo (was missing an LFO)
- Fixing delay to be stereo
- Adding flutter rate and amount params to delay to simulate Tape Delay
- Fixing Tube so it goes beyond than just warming a little bit the sound
