Generate FHIR Medication resources for potential formulary use

[jrlegrand]

Proposal

Utilize data in SageRx to generate a FHIR resource or resources to be used in applications such as Medplum or any application that consumes FHIR data.

Demo of how this could be done using Medplum: https://github.com/codyebberson/medplum-medication-data-demo

Could dump to JSON or store as a "Project" in Medplum.

One option is the new-ish MedicationDefinition
https://hl7.org/fhir/R4B/medication-definition-module.html

There's also Medication and MedicationKnowledge. Main issue with these is that they don't seem to have a differentiation between package and product like MedicationDefinition.

There are other repos out there that tried to do this, but they are 5+ years stale and written in Java...

Rationale

I think this is a pain point for many that they just deal with. People "load RxNorm" but what does that really mean? We could provide an off-the-shelf solution for working with medication formularies in FHIR format.

Could also be a feature of Formulary.
