Add support for IN2, additional mappings for IN1

[Brian Cragun]

Add additional fields for Coverage / RelatedPerson from IN2 record.

IN2.2 (SSN) to RelatedPerson.identifier
IN2.63 to RelatedPerson.telecom

IN2.72 as backup relationship for IN1.17.
NOTE: special rules apply for interpreting the direction of the relationship as input and mapping to the direction of the relationship expected by the FHIR field.

Interested parties should read detailed notes in v2ToFhirMapping.yml IMPORTANT NOTES ON RELATIONSHIP MAPPINGS

• Coverage.identifier from IN2-6
  • Coverage.identifier.type:
    system= http://terminology.hl7.org/CodeSystem/v2-0203
    code=MC
    display=Patient's Medicare number
• Coverage.identifier from IN2-8
  • Coverage.identifier.type:
    system= http://terminology.hl7.org/CodeSystem/v2-0203

• IN1.35 to Organization.identifier. This identifier will have a value only, no system or type. (PR A)
• Coverage.payor create a separate Organization from IN2.25
  • IN2.25.1 is used to set Organization.id.
    • If a tenant is set, the id value should be .<IN2-25.1>
    • If a tenant is not set, the id value will be just IN2-25.1
• Organization.identifier using

.4 identifier.system (urn:id:25.4)
.5 identifier.type.code
.7 identifier.period.start
.8 identifier.period.end

if subscriber=self, use IN2.2 as fallback to populate SSN patient identifier if PID-19 is empty

IN2.6 to Patient.identifier.type.coding.code=MC

IN2.8 to Patient.identifier.type.coding.code=MA

If subscriber=self, use IN2-61 for Patient.identifier.type.coding.code=MB, fallback to IN1-36:
