Construct FITS-WCS from WCS Wrappers about ndcube HOT 2 OPEN

ping @jmason86 @Cadair

I think these 3 functions would solve your problem @jmason86 and should not be an unreasonable amount of work. Your SunCET pipeline could then use NDCube natively and be significantly simplified. And you could write the end product our to FITS in only a couple of lines of code.

While I think writing the convert-back-to-fits functionality is good and should be done, I think there's a better way of doing this holistically.

Ideally, when constructing a low level wrapper, the wrapper class should see if it can modify the input WCS rather than return an instance of itself. Ideally (I think), this would be dispatched out to the input WCS (i.e WCS._resample_wcs) which could return NotImplemented if the operation can not be done on that particular WCS.

I think this would be a good addition to the APE 14 API to extend it into analysis operations.
