tfprobability 0.15.1

0.15.0

updated install_tfprobability() to use latest release.
vi_mote_carlo_variational_loss() gains a importance_sample_size arg.
sts_one_step_predictive() gains a timesteps_are_event_shape arg.
Deprecations:
- tfb_affine_scalar()
- variational_loss_fn arg in vi_fit_surrogate_posterior
