add a complete action embedder that can accept any number of discrete actions with variable bins as well as any number of continuous actions, pooled and added to the agent token as described in the paper (seems like they fixed that horrendous hack in dreamer v3 with sticky action)

add the noising of the latent context during generation, technique i think was from EPFL, or perhaps some google group that built on top of EPFL work
