User Story

As ReportStream, I need the ability to de-identify HL7 v2 messages, so that I can remove sensitive data from messages.

Description/Use Case

The updated RADx MARS HL7 v2 format on how to de-identify messages can be found here: https://www.nibib.nih.gov/covid-19/radx-tech-program/mars/hl7-message-de-identification-for-sending-to-hhs-protect

Dev Notes

Try to use existing Github SOP documentation and identify gaps. https://github.com/CDCgov/prime-reportstream/tree/master/prime-router/docs
