Description

All over Mava we have statements like tree.map(lambda x: x[jnp.newaxis], pytree) I think it would make it a lot clearer if we had an add_batch_dim method in utils.jax_utils

Contributor guide

Research direction
Create a utility function in `utils/jax utils.py` that takes a pytree and returns the same pytree with a new batch dimension added using `jax.tree.map(lambda x: x[jnp.newaxis], pytree)`. Ensure to import `jax.numpy as jnp` and `jax.tree util`.
