Danger zone: low-level pointer operations — nanoarrow_pointer_is_valid

The nanoarrow_schema, nanoarrow_array, and nanoarrow_array_stream classes are represented in R as external pointers (EXTPTRSXP). When these objects go out of scope (i.e., when they are garbage collected or shortly thereafter), the underlying object's release() callback is called if the underlying pointer is non-null and if the release() callback is non-null.
