I think the failing tests might be related to the version change of jax from 0.4.35 to 0.4.36. |

This PR adds a utility function
log_densitiesto theinfer.utilmodule to evaluate log densities for individual sites of the model. This is mostly useful for debugging and inspecting individual contributions to the summed log density and ELBO.I've moved type annotations from the docstring to the signature for
log_densitywhich now callslog_densitiesbut otherwise remains unchanged.
