Imported public/acc_tcga_pan_can_atlas_2018 from this PR into hub.cbioportal.org as a spot check (only 1 of the 32 studies touched here — importing all 32 would take hours).

Patient view: https://hub.cbioportal.org/patient?studyId=acc_tcga_pan_can_atlas_2018&caseId=TCGA-OR-A5J1

The Resources tab should show the new IDC SLIM viewer link.
