This patch release improves some cases related to new functionality in PyO3 0.22.
PartialEq<bool> has been added for Bound<'py, PyBool>.
The #[pyo3(submodule)] attribute has been added for declarative modules to stop submodules from generating an external C symbol for importing the submodule directly (which is typically never used). Declarative modules will also now correctly add items annotated with full-path attributes like #[pyo3::prelude::pyfunction].
The #[pyclass(eq)] option will no longer raise a TypeError on comparison against types not in the signature.
A #[setter] in #[pymethods] with an Option<T> input will no longer raise a deprecation warning.
A regression has been fixed in conversions for 128-bit integers on big-endian platforms.
