Validate augmentation binding class

Validate augmentation binding class

LazyDataObject's DataObject.augmentation(Class) implementation
needs to re-validate if the augmentation we are about to decode
matches user-requested augmentation.

This is needed to ensure that we do not return shape-equivalent
augmentation, such as when the same augmentation is applied to
multiple instantiations of the same grouping. In such a case
type-safety indicates that the grouping can have either of the
augmentations, yet in reality its validity depends on
instantiation.
