You don't use the value of cls anywhere. Is this line superfluous?

The class kExternalTypedDataUint8ArrayCid needs to be registered in the class
table so that it is available when a token stream is read and hence we set that
up here by calling Class::NewExternalTypedDataClass.
I added a comment above to make this clear.
