Function namespaceOf

The namespace a node belongs to, seen through the published Namespace.

BaseNode.namespace is declared in node-opcua-address-space-base, which cannot name the alarm-and-condition, data-access and machine-state methods this package adds without depending on it. So a caller holding only a node saw the narrower INamespace, and reaching instantiateAlarmCondition meant asserting the type at every call site.

The same mismatch was already corrected for AddressSpace.getOwnNamespace(), which used to return the narrower interface and hide those methods. This closes the remaining case: the assertion happens once, here, where both types are in scope.

const alarm = namespaceOf(deviceNode).instantiateAlarmCondition(alarmType, {
    browseName: "FailureAlarm",
    conditionSource: deviceNode,
    inputNode: deviceHealthNode
});
