Added OBX Datatype Support

[JohnNKing]

Based on the findings from #777, improve OBX mappings for datatypes that currently lose field data.

[JohnNKing]

As identified during transformation testing today with a CA sample ORU, this effort is still needed. Specifically, we see issues with:

1. The CE data type: OBX.3 and OBX.5 are lost
2. TN is rejected by RS (if changed to XTN, OBX.5 is lost)
3. OBX.6: For μmol, 'μ' has an encoding issue in the resulting HL7
