Fix the NTupleWriter algorithm to handle `DataObject*` and `AnyDataWrapperBase*` Correctly in `BranchWrapper`

Refactored BranchWrapper::setBranchData to properly handle cases where casting to AnyDataWrapperBase* fails. Previously, the code raised an exception when the cast failed, which was incorrect, as in some (if not most) cases we actually want to store the DataObject* directly. Now the code handles both cases: using AnyDataWrapperBase* when available, and defaulting to DataObject* when the cast fails.
