First round of NPM package loading functionality for Measures and Libraries

[lukedegruchy]

• Introduce NpmPackageLoader as an interface with default method to enforce the NPM loading contract
• This version of NPM functionality loads FHIR resources directly, and can theoretically support loading any FHIR resources, though in practice we want to limit this to Measures, Libraries, PlanDefinitions, etc
• Make this FHIR version agnostic, as it supports both R4 and R5.
• Add an NpmNamespaceManager which captures the function to extract namespaces from NPM packages
• Add R4 and R5 tests verify the contract for loading NPM packages works with packages built for both R4 and R5
