Improve support for images where compositeChannelCount != numChannels

We have some images that would display well when composite channel count != numCHannels. We have a 12 channel image (Day 1 Naked NB positive 1-2007-0055.zvi) which would display well with compos chan count == 3. The existing slider manipulation and display code needs to be updated to support this.

First of all, it needs to be possible to individually toggle each channel in composite mode. We will have to think about the best UI to support this. In ImageJ1, the Channels Tool window provides a separate checkbox for each channel. We could do something similar, perhaps.

However, even with such a feature, it would not automatically "group" the channels together as appropriate. I think what we really need is for each channel to belong to a group. Then for the 12-channel dataset, we could group channels 1-3, 4-6, 7-9 and 10-12 into four distinct groups. The channel compositor would take care to toggle all channels on/off in the same group whenever the active channel changes. This would provide the desired behavior. But of course the user still needs to be able to override the behavior as necessary.
