Binding Data Codec: Equivalent augmentation resolution is not optimal

Copy via Builder allows to copy augmentations, which were generated for other instantation of grouping.

Equivalent augmentation algorithm, which decides that same augmentation is present in newer place heavily relies on reflection comparison of generated classes and that comparison is run each time user tries to retrieve augmentation from such LazyDataObject.

Result of comparison should be cached to speed-up other lookups. This is doable due to immutable nature of Java classes.
