Feature/water layers

[z3nth10n]

I create a feature to have both water layers from blue marble next generation: https://neo.gsfc.nasa.gov/archive/bluemarble/bmng/

The configuration I have (on ddd.conf) is this:

    {'path': '/root/earthplusplus/elevation/ocean/ocean-landmask3.tiff',
     'crs': 'EPSG:4326',
     'resolution_m': '207.08403036450474',
     'bounds': [-180.0, -90.0, 180.0, 90.0],
     'bounds_wgs84_xy': [-180.0, -90.0, 180.0, 90.0],
     'is_water_mask': True,
     'land_value': 255,
     'water_value': 0
    },  # (207.084 m/pixel)
    {'path': '/root/earthplusplus/elevation/ocean/ocean-test.tif',
     'crs': 'EPSG:4326',
     'resolution_m': '414.16639569346967',
     'bounds': [-180.0, -89.99928, 179.99986, 90.0],
     'bounds_wgs84_xy': [-180.0, -89.99928, 179.99986, 90.0],
     'is_water_layer': True
    },  # (414.166 m/pixel)

I created the right GeoTiff by using QGis, rescaling the minimum and maximum values and rasterizing the binary file for the landmask using Pillow in Python.
