public interface RxDogTagTaggedExceptionReceiver extends RxDogTagErrorReceiver
RxDogTagErrorReceiver.onError(Throwable). Note that this will always be tried directly, and no guarded delegate
behavior will be attempted even if RxDogTag.Builder.guardObserverCallbacks(boolean) is
enabled in configuration.
NOTE: RxDogTag exceptions are always OnErrorNotImplementedExceptions, as these have special behavior as an escape hatch in RxJava
internals. This exception will have no "cause" property if the original exception was not already
an OnErrorNotImplementedException. If it was, which is unusual, it is reused with its
original cause (if any) and has its stacktrace modified.
