Sink (callback) for namespace definitions.

Called whenever a prefix is defined in the serialisation.

typedef SerdStatus (*SerdStatementSink)(void *handle, SerdStatementFlags flags, const SerdNode *graph, const SerdNode *subject, const SerdNode *predicate, const SerdNode *object, const SerdNode *object_datatype, const SerdNode *object_lang)
