We need read/write methods to FITS (or other, I guess).

The easy but wasteful approach is a cube - we can steal the WCS from data and just write. Read plane 0 and the (0,0) spectrum or something.

Less wasteful would be SCALE in header plus two extensions, one for spatial variations, one for spectral. But this requires a bit more WCS noodling on both ends.

Thoughts?
