Node engine limitation

Previously hearth was limited to using node >= 6.9.0 and < 9.0.0 because using anything newer
would cause the build process to fail. The issue was actually with fhir->libxmljs->nan and using
libxmljs >= 0.18.8 made it possible to remove the engine limitation.

Now it works with node v14.18.1
