Update notebook, bands no more available

[clausmichele]

Currently if we request specific bands an error is thrown:

collection      = 'SENTINEL1_GRD'
spatial_extent  = {'west':bbox[0],'east':bbox[2],'south':bbox[1],'north':bbox[3],'crs':'EPSG:4326'}
temporal_extent = ["2018-07-01", "2018-07-03"]
bands           = ["VV","VH"]

s1 = conn.load_collection(collection,spatial_extent=spatial_extent,bands=bands,temporal_extent=temporal_extent)

MetadataException: No band dimension

@soxofaan is this the expected behavior after the collection unification?

[soxofaan]

confirmed, this the cube:dimensions data is not merged properly yet when combining https://openeocloud.vito.be/openeo/1.0/collections/SENTINEL1_GRD and https://openeo.eodc.eu/v1.0/collections/SENTINEL1_GRD

[soxofaan]

Fixed the problem. It should work now against the dev instance https://openeocloud-dev.vito.be/openeo/1.0/

deploying to production will probably not be for this week

[clausmichele]

I confirm that this issue has been fixed.
