Clean up HL7v2 -> FHIR -> HL7v2 mappings

[jack-h-wang]

User Story

As a RS engineer, I want to ensure all FHIR mappings are completed so that they are maintainable and concise.

Description/Use Case

With #14249 complete there are HL7v2 <-> FHIR mappings that we should now be able to complete that were not covered by the message classes we previously utilized. This is to go back and add any mappings relevant to RS that might be missing and clean up any work that might not be consistent with other work.

Risks/Impacts/Considerations

Dev Notes

This ticket is to look into the following specifically:

• Complete mappings for PRT
• Complete mapping for OBX-33

Acceptance Criteria

• [ ] PRT and OBX Updated
