Value systems from Code system https://terminology.hl7.org/5.5.0/CodeSystem-hl7TermMaintInfra.json.html are not expanded correctly

[aswathikrishnan24]

Describe the bug

The Value sets :
356 http:https://terminology.hl7.org/ValueSet/mif-conceptRelationshipKind
357 http:https://terminology.hl7.org/ValueSet/mif-conceptRelationshipReflexivity
358 http:https://terminology.hl7.org/ValueSet/mif-conceptRelationshipSymmetry
359 http:https://terminology.hl7.org/ValueSet/mif-conceptRelationshipTransitivity

Belonging to Code system : https://terminology.hl7.org/5.5.0/CodeSystem-hl7TermMaintInfra.json.html are not expanded.

Value set expansion of http:https://terminology.hl7.org/ValueSet/mif-conceptRelationshipTransitivity (value set 359) should pick all codes under "MIF-ConceptRelationshipTransitivity" and then exclude itself which is MIF-ConceptRelationshipTransitivity .

All codes :

1. MIF-ConceptRelationshipTransitivity
2. transitive
3. antitransitive

The expanded codes should be

1. transitive
2. antitransitive

In the Codes table, the corresponding codes are not present.
Value set IDs 356 - 359 have no codes

To Reproduce
Steps to reproduce the behavior:

1. Install firely-car tool
2. Generate car file from us core 5.0.1 package.

{
    "name": "Us-core-test-5.0.1",
    "version": "0.1.0",
    "description": "describe your package",
    "author": "supply your name here",
    "dependencies": {
      "hl7.fhir.us.core": "^5.0.1"
    }
  }

4. Verify the Value set 359 from Value set table
5. Verify if the codes are generated in Codes table

Expected behavior
The expanded codes should be

1. transitive
2. antitransitive

Version used:

• FHIR Version: R4
• Version: Firely-car tool 2.1.2

Looking at this, we seem to throw away the children of the codes when we throw away the parent.

Todo:

• When we delete a code, check for children
• If children, then put them on the level of the code you want to delete and delete the original code.

307 http:https://hl7.org/fhir/ValueSet/encounter-participant-type also seems to expand incorrectly because of the same issue.
