fits reader is lazy
...
The fits reader is now lazy, and reads out whole tiles when it can.
Previously it read a scanline at a time, and used WIO.
We read in planes and combine with a set of im_bandjoin().
Use an im_flipver() at the end to get rows in the right order.

fits reader is now lazy
...
The fits format reader now uses fits_read_subset() to erad pixels
lazilly. There are a few unresolved issues though:
- getting some streaking, try putting a lock around the read
subarea call, perhaps it can't thread?
- add a tile cache, cf. tiff
- test colour read with valgrind
- ask Doug for a test colour image
- read whole tiles, if the alignment is right, again see tiff reader
- test performance
- remove the old scanline reader?
