516 ON-HOLD Prepend resource type (eg Library or Measure) to resource file extension

[baseTwo]

Work for #516

⚠️ DO NO MERGE -- Must be discussed at September WGM as this is not per spec.

Prepend resource type (eg Library or Measure) to resource file extension, since there could be overwrites on the same file when the resource is both

eg.

AAB_Reporting.library.json
AAB_Reporting.measure.json

Must have settings to enable this or not

[baseTwo]

Think about other formats e.g. Having the resource type name as part of the file extension, eg. Reporting.Library.json.
Consider that this file name change effects resource loading of dependencies.

@baseTwo Based on this doc:
https://build.fhir.org/ig/HL7/cql-ig/conformance.html
CQL library source files SHOULD be named CQLLibraryName-Version.cql

I think that we should go with the format when writing to file system
Library-LibraryName-Version.json
Measure-MeasureName-Version.json

This way it mimics more closely the source cql recommendation.

I think we should merge this change with the modification stated above, so that the measure building isn't overwriting the library files. We agreed at WGM that building measures from CQL annotations was a good value add to the SDK. For now, just fixing the "bug" of overwriting is more important.

The settings part and output still needs design. I have some code started for this which I will submit in a future PR.
