DataRequirementProcessor does not account for overloaded CQL functions while gathering the DataRequirements #1366

DataRequirementProcessor provides a config option named collapseDataRequirements to remove duplicates. However, it appears that while removing the duplicates, it doesn't consider the overloaded functions. Here's the piece of code that does the filtering https://github.com/cqframework/clinical_quality_language/blob/5d9ccd6b0c0e7ffc0604c50473651f934ff916c7/Src/java/elm-fhir/src/main/java/org/cqframework/cql/elm/requirements/ElmRequirements.java#L247

This makes effectiveDataRequirements incomplete. Also, effectiveDataRequirements are used to generate the Human readable in liquid templates, it misses out a bunch of overloaded functions. Could someone please take a look at this or provide any suggestions?
