Potential Solution

Throw exception if SetWarmup is called when IsWarmingUp has already been flipped to false. The message should tell the user that this method should

Heston model has accurate density approximations for European option prices, which are of interest.

The module implementing this method should live under tf_quant_finance/volatility/heston_approximation.py. It should support both European option puts and calls approximations. Tests should be in heston_approximation_test.py in the same folder.
