refactor: re-export autoconf config surface from library __init__

Expose the autoconf (Nerves) configuration/serialization surface as a
deliberate public API of each science library, so workspaces and downstream
code can `from autolens import conf` (and jax_wrapper, setup_colab,
setup_notebook, fitsable, with_config, dictable/fitsable/test_mode helpers)
rather than importing the `autoconf` package directly. This keeps the config
layer an implementation detail behind the library namespace.
