• Closes #52
• maybe addresses #51
• Add GeoBox.compat to convert to datacube version of GeoBox
• In reproject use nan as fill value for float32 outputs if output nodata is not configured
  • fixes boundary effects when plotting float32 input on a map
• In colorize handle nodata values properly for non float inputs
  • fixes boundary effects when plotting non-float inputs on a map
• In colorize drop nodata attribute on the output array
• In geobox display support non-epsg authority codes like ESRI
• Better Dask support for GeoBox, CRS and GeoBoxTiles classes (fixes hashing)
• Add GCP extraction utilities
• Add Geometry[Point] -> XY[float] conversion
• Deprecated Geometry.__iter__ interface to follow shapely deprecation of that
