An interface for layer post-processing handlers for execution following a processing algorithm operation.
Note that post-processing of a layer will ONLY occur if that layer is set to be loaded into a QGIS project on algorithm completion. See QgsProcessingContext::layersToLoadOnCompletion().
Algorithms that wish to set post-processing steps for generated layers should implement this interface in a separate class (NOT the algorithm class itself!).

Post-processes the specified layer, following successful execution of a processing algorithm.
This method always runs in the main thread and can be used to setup renderers, editor widgets, metadata, etc for the given layer.
Post-processing classes can utilize settings from the algorithm's context and report logging messages or errors via the given feedback object.
In the case of an algorithm run as part of a larger model, the post-processing occurs following the completed execution of the entire model.
Note that post-processing of a layer will ONLY occur if that layer is set to be loaded into a QGIS project on algorithm completion. See QgsProcessingContext::layersToLoadOnCompletion().
