No static backing property for the ModelInspector static property

[brianpos]

The modelinspector property does not have a static backing property to effectively cache the value to remove future calls from re-scanning the assemblies

firely-net-sdk/src/Hl7.Fhir.Shims.STU3AndUp/Model/ModelInfo.cs

Lines 262 to 274 in ffb6d67

	public static ModelInspector ModelInspector
	{
	get
	{
	var inspector = ModelInspector.ForAssembly(typeof(ModelInfo).GetTypeInfo().Assembly);
	if (inspector.FhirRelease != Specification.FhirRelease.STU3)
	{
	// In case of release 4 or higher, also load the assembly with common conformance resources, like StructureDefinition
	inspector.Import(typeof(StructureDefinition).GetTypeInfo().Assembly);
	}
	return inspector;
	}
	}
