LeafSpec
The spec of a single leaf: TreeSpec(*).
:func:~clika_runtime.pytree.tree_flatten returns an instance of this class
when the tree is a leaf, so isinstance(spec, LeafSpec) tells a lone
value from a container.
pytree.tree_structure(3) TreeSpec(*) isinstance(pytree.tree_structure(3), pytree.LeafSpec) True
