Add direct reference codes to manifest during $release

[Chris0296]

Update $release operation to gather any direct-reference codes referenced by component measures and add them to the manifest, using the directReferenceCode extension slice on the root of the release manifest.

Functionality handles STU4/STU5+, works with cqfm-directReferenceCode (STU4) and cqf-directReferenceCode (STU5) in the Measure source, output is always cqf-directReferenceCode extensions in the Manifest because cqfm-directReferenceCode isn't allowed in a CRMIManifest.

Formatting check succeeded!

Copying question from the related issue here:

"Is it safe to assume that STU4 will always have 'cqfm-directReferenceCode' and STU5 will always have 'cqf-directReferenceCode' or are both extension URLs valid for both versions?"

This implementation assumes the former.

Test needs fixup on the cqf- extension spelling, it's an extension pack extension, so it's URL is just http://hl7.org/fhir/StructureDefinition/cqf-directReferenceCode, (i.e. remove the us/cqfmeasures part from the canonical)
