Model is not a DAG

In testing the schematic refactor in #322 we get the following warnings re loops in the data model. These will become errors in future versions of schematic, so we should look to implement changes to the data model to remove these loops

• we found a loop between: RPPALevel2 and HTANRPPAAntibodyTable
• we found a loop between: MelanomaTier3 and Patient
• we found a loop between: SarcomaTier3 and Patient
• we found a loop between: PancreaticCancerTier3 and Patient
• we found a loop between: Patient and BreastCancerTier3
• we found a loop between: Patient and SRRSClinicalDataTier2
• we found a loop between: Patient and NeuroblastomaandGliomaTier3
• we found a loop between: Patient and LungCancerTier3
• we found a loop between: Patient and ColorectalCancerTier3
• we found a loop between: Patient and ClinicalDataTier2
• we found a loop between: Patient and AcuteLymphoblasticLeukemiaTier3
• we found a loop between: Patient and ProstateCancerTier3
• we found a loop between: Patient and OvarianCancerTier3

@mialy-defelice advises removing Depends On Component from most of these. This aligns with how we have other components set up
