Incompatibility with tensorflow 2.16

[pablo2909]

Hi,

I get AttributeError: module 'tensorflow' has no attribute 'estimator' when trying to import tensorflow_gan. I believe this is because the recent release of tensorflow (2.16) removed tf.estimator. Should then version 2.15 be a requirement to use tfgan ? In addition tensorflow_probability should then be version 0.23

Thank you for looking at this :)
