Fix `__len__` of empty Product sweep to match actual length #6575

Closed maffoo closed 6 months ago

maffoo commented 6 months ago

An empty cirq.Product() sweep yields one empty param resolver, but was reporting a length of 0 when calling __len__. This fixes the __len__ computation so it agrees with the actual length of the sweep when iterating.
