v0.6.3 - Go FHIR validation library

Go

• Upgrade protobuf dependency from github.com/golang/protobuf/proto to google.golang.org/protobuf/proto internally
  • Overall marshaller/unmarshaller performance is improved
  • Upcoming change will migrate the public API
• Introduce fhirvalidate package. This splits out most of the validation that was being done in the unmarshaller so it can be performed independently on the FHIR protos. Consequently, NewUnmarshallerWithoutValidation is now more lenient.

Python

• Add //py/distribution with a README.md, Dockerfile, and shell script for building and testing sdist and bdist_wheels from source for google-fhir

Bug fixes

• Fixes #25, where a dangling comma was being added when an empty ContainedResource was written to JSON
