Title: First draft of generalized WCS standard.

WIP.

At this point, I'm deliberately trying to avoid some of the rigidity of FITS WCS. All FITS WCS have a `CDELT` offset and `PC` matrix, for example, as the "core" concept. But I think that's limiting. What if you want to correct on the focal plane first, for example?
