Sensors

Add a new sensor

1. Add the name of the constellation (or the name of the sensor) to the list of Constellation in common/naming.go.
2. Call go generate ./...
3. Update the functions of common/naming.go.
4. In catalog/catalog.go, adapt DoTilesInventory method in order to be able to interpret the new constellation.

The next step might be to add a catalogue provider or an image provider for this sensor.
