Medication Adminstration resource for Insulin value

A reduced format of this resource will be sent from Confidence. See the section Insulin data - reduced FHIR. The facade needs to further expand that resource by adding the other relavent fields as per our implementation guide. Details are provided in the comments below in green.

Below are examples of Medication adminstration resource having Insulin information in expanded FHIR format
