• Add support for some more kinds of longitude arrangements seen in planetary
  maps: "zero left" where the longitude = 0 line is on the left edge of the
  image, rather than in the center, and "zero right" which is comparable except
  that longitude increases to the left, as usually seen in sky maps, rather than
  to the right (#75, @pkgw). These are available in the CLI with the new
  plate-carree-planet-zeroleft and plate-carree-planet-zeroright projection
  types.
• When creating planetary TOAST maps, actually use the planetary TOAST
  coordinate system by default (#75, @pkgw).
