OpenTargets Get Credible Set Colocalisation

Retrieve GWAS/QTL colocalisation evidence for a credible set (by studyLocusId) from OpenTargets. Returns the colocalisation count and rows, each with the method (COLOC, COLOC_PIP_ECAVIAR, etc.), the posterior probability h4 of a shared causal variant, the colocalisation posterior probability clpp, numberColocalisingVariants, and the other colocalising study locus (studyLocusId, study type/id). Use to link a GWAS signal to a molecular QTL.
