Description
Hi,
Is the cdf() function from distributions.NormalInverseGaussian currently working? or is it in the pipeline? as I seem to be getting the following error when attempting to use it:
NotImplementedError: cdf is not implemented: NormalInverseGaussian
I see it appears in the docs here:
https://www.tensorflow.org/probability/api_docs/python/tfp/distributions/NormalInverseGaussian

Research direction
Start by checking the NormalInverseGaussian distribution API and its documented cdf entry against the current implementation. Confirm whether the missing behavior is an unimplemented feature or an incorrect documentation claim, then define the expected cdf behavior and verify that calling cdf no longer raises NotImplementedError.
