GeoWombat DataArray accessor

GeoWombat extends xarray.DataArray through a registered .gw accessor. Once an array is opened with geowombat.open(), every GeoWombat method and property is reached through this accessor (for example src.gw.transform or src.gw.ndvi()), which keeps the DataArray namespace clean while making the functionality discoverable via tab-completion.

The properties below describe the geospatial attributes of the image. For the complete list of accessor methods and properties, see the GeoWombatAccessor entry in the API reference.
