Specifics to data conversion

• To ensure needed anonymity the Cardano L1 Publisher replaces the cost centers with the parent cost center. This ensures the precise data is still available, but the cost center itself is not directly visible on the blockchain. Additionally, to reduce the data size transaction items will be aggregated within this publisher, if all fields are equal except the amount. The amounts will be summed then.
