Consider adding a 200m bathymetry dataset.

It was suggested that the 200m IBCAO bathymetry be added. We currently use the GEBCO grid at 400m clipped to the QGr background boundary. We could probably choose to add GEBCO at 200m.

there is a 200m IBCAO dataset here . The GEBCO grid (from which IBCAO is based), is available at a resolution of 0.004166666666667 degrees lat/lon. Our gdalwarp step sets the resolution of our reprojection of this dataset to 400x400 meters, to be consistent with the original 400m IBCAO grid we included in v2. We could change this.

#584 addressed using the full GEBCO grid for v3.

This suggestion received from feedback for QGreenland v3 alpha4 (#674)
