This PR adds a minimal TreeSpec implementation to dm_env to support structured
action and observation specifications using Python dataclasses. This directly
addresses Issue #13 ("Tree Spec").
✔ What is added
TreeSpecclass in specs.py._generate_tree_value()helper to generate valid test values.test_tree_spec_generate_value.✔ Why this is useful
Many JAX-based RL environments define structured I/O using dataclasses.
While dm_env already supports tuple/dict specs, dataclass-based specs were not
recognized, causing type checking and clarity issues. TreeSpec provides an
explicit and type-safe way to represent these structures.
✔ Compatibility
This feature is fully backward-compatible and does not modify any existing spec
behavior. All existing tests pass (166 passed).
