Handle *empty* BigInt64Array/BigUint64Array in the isNumberArray helper

Browse source 
The current checks would accidentally allow *empty* BigInt64Array/BigUint64Array, which we can fix by instead checking directly for those types.
This should be fine since those types are available in all environments that we support, see:
