FHIR Data Absent Reason to C-CDA NullFlavor

FHIR Data Absent Reason to C-CDA NullFlavor. Adapted from https://hl7.org/fhir/R4/cm-data-absent-reason-v3.html but several key changes have been made. Note that this prior concept map (from R4) is no longer included in current FHIR build.

Source Code	Source Display	Equivalence	Target Code	Target Display
`unknown` http://terminology.hl7.org/CodeSystem/data-absent-reason	Unknown	wider	`NI` http://terminology.hl7.org/CodeSystem/v3-NullFlavor	NoInformation	In CDA, 'UNK' means 'a proper value is applicable, but not known.' Guidance has been to use this when the value is known to exist and to use the broader 'NI' when no specific information about why the value is unknown. FHIR's data absent reason of 'unknown' better maps to 'NI'.
