Investigate alternative jax based samplers available since bambi: 0.15.0

[AlexanderFengler]

Version 0.15.0 of Bambi adds support for a lot of extra samplers, via deeper integration with the bayeux package.

We need to properly tests that we support this (this will essentially be a robustification exercise on the behavior of our likelihoods).

To close this issue, essentially try to replicate this notebook via HSSM.
