Title: Move to common ArgReader and ArgWriter classes.

This change fixes a number of problems with the existing Reader/Writer traits,
as well as their subclasses. In particular:

1. Unifies the various ARG readers/writers
2. Fixes some bugs with float32/float64 rasters
3. Fixes some other bugs with int16 rasters
4. Adds some ARG tests
5. Allow the "raster reader" to correctly handle types other than int32.
6. Allow tiled rasters to correctly read/write various tile formats

There is still some work to be done on cleaning up the Reader/Writer
interfaces, as well as possibly migrating things like the ascii grid and
geotiff formats away.
