dependencies	A dependency between processing blocks means that one processing block requires something from the other processing block to run - typically an intermediate Data Product. This generally means that The dependent processing block might only be able to start once the dependency has been fulfilled Data associated with the dependency must be kept alive until the dependent processing block is finished. As processing blocks might have many different outputs, the dependency “kind” can be used to specify how this dependency is meant to be interpreted (e.g. “visibilities”, “calibration”…)
