Allow the VST multi-panner to place all 6 channels

While the VST multi-panner in Cubase 9.5 is very useful for mapping 2-channel sound in to surround, it is not so useful for remapping existing surround sources. Sometimes it is desirable to change the orientation or focus of the additional channels, and currently the plugin will not allow that, though it appears to be capable of doing so in Nuendo. I think this would be a useful feature to bring to Cubase.
