Namespace error when invoking external dependencies in CQL to ELM translation

[JunaidUK]

When translating CQL to ELM, the translator fails due to a namespace resolution error. Initially the assumption was that it was an issue with the VSCode CQL plugin, but upon further digging the issue exists when invoking the translation commands from the command line directly to the cql-to-elm-cli tool.

A reproduction of the issue (and setup instructions) can be found here: https://github.com/reason-healthcare/crmi-reusable-cql/blob/unresolvable-namespace/README.md. The unresolvable-namespace branch has the cli scripts and libraries so that this is easily reproducible.

The scripts and libraries were built using ./gradlew installDist in the java-quickstart directory, and the command to invoke the translation is ./cql-to-elm-cli/bin/cql-to-elm-cli --input ./DependencyIG/input/cql/DependencyLibrary.cql.

This error exists in the WHO Immunizations IG when trying to convert the IMMZElements.cql file, which has a namespaced dependency on FHIR Common
