Ensure extractChannel sets a relevant colourspace

See original GitHub issue

We have ML project, and we would like to transform a large set of image to black/white based on a colorband (the C band from the LHC) for now.

I played with the toColorband('lhc').bandbool(...) but it while the ‘or’ ‘eor’ operations seems to work, I do not see how I can go to bw base only on one band.

I assume we cloud ask the Buffer, and process it in JS, but we would like to avoid that given our volume of images to be processed.

@lovell I have been swamped, but I will test it soon. Really appreciate the responsiveness and the quality of this lib. I will try to find time to blog about it. I really like the “instructions builder” approach.
