Hydra-zen

See [changelog](https://mit-ll-responsible-ai.github.io/hydra-zen/changes.html) for details.

This release:

- Improves hydra-zen's [automatic type refinement](https://mit-ll-responsible-ai.github.io/hydra-zen/structured_configs.html#automatic-type-refinement). See 84 for details
- Cleans up the namespace of `hydra_zen.typing`. See 85 for details

**Compatibility-Breaking Changes**

- The protocol ``hydra_zen.typing.DataClass`` is no longer available in the public namespace, as it is not intended for public use. To continue using this protocol, you can import it from ``hydra_zen.typing._implementations``, but note that it is potentially subject to future changes or removal.

This is hydra-zen’s first stable release on PyPI! Although we have not yet released version v1.0.0, it should be noted that hydra-zen’s codebase is thoroughly tested. Its test suite makes keen use of the property-based testing library Hypothesis. Furthermore, 100% code coverage is enforced on all commits into `main`.

We plan to have an aggressive release schedule for compatibility-preserving patches of bug-fixes and quality-of-life improvements (e.g. improved type annotations). hydra-zen will maintain a wide window of compatibility with Hydra versions; we test against pre-releases of Hydra and will maintain compatibility with its future releases.
