Summary

Marking this as draft for now since it is branched off of #160. I made that the base branch so the code diff is clean to look at here

Fixes #146

This PR adds more information to all population and stratifier results when defined on the Measure group

New behavior

If a population has an id, that id will be included on the root populationResults for that population, and on any populationResults for individual episodes in the episodeResults
If a population references another using cqfm-criteriaReference, the id of that referenced population (aka the valueString of that extension) will be included on all relevant results similar to above
If a strata in the Measure Group's stratifier has an id, that will show up as strataId on all stratifier results (including for individual episodes)

New helper function for adding populationId and criteriaReferenceId to a given populationResult
Anywhere a populationResult is created, add the relevant IDs using the above function
Detect when a strata has an ID and ensure it is present on all created stratifier results

Unit tests are the best bet for the stratifier stuff
For everything else, test detailed results using the following cases (the test cases provided in #152 and #160 might be useful here)
- Boolean measure with population IDs
- Boolean measure with a measure observation (uses criteriaReference)
- Episode measure with population IDs
- Episode measure with a measure observation (uses criteriaReference)

For the above cases, you should see IDs and criteriaReferenceIds present on the results where appropriate
