Relating horizons to seismic volumes requires workaround
Seismic horizons are related to the seismic volume(s) through SeismicTraceDataID, srn:work-product-component/SeismicTraceData:[^:]+:[0-9]*$". The value of the SeismicTraceDataID is generated at ingestion. The value will be different for each cloud provider, so the load manifest for horizons can not be populated with the value in advance. A workaround is to prepare the manifests after loading seismic volumes and recording the SeismicTraceDataIDs
