addFeatureOverrideProvider Method

Add a FeatureOverrideProvider to customize the appearance of Features within the viewport. The provider will be invoked whenever the overrides are determined to need updating. The overrides can be explicitly marked as needing a refresh by calling setFeatureOverrideProviderChanged. This is typically called when the internal state of the provider changes such that the computed overrides must also change.
