Bumps pyo3 from 0.16.4 to 0.20.3.

Release notes

Sourced from pyo3's releases.

PyO3 0.20.3

This is a stability & compatibility release to fix a couple of minor compilation edge cases from PyO3 0.20.2.

The portable-atomic dependency has been added to resolve compile failures on platforms without 64-bit atomic support.

A maximum Python version check (currently for Python 3.12) has been added to prevent using old PyO3 code against future Python versions beyond the supported range.

Thank you to the following users for the improvements:

PyO3 0.20.2

This release corrects a failure to compile of the either feature when the experimental-inspect feature is not enabled.

It also adds backwards-compatibility for pyo3 0.20.0 to build against pyo3-build-config 0.20.2, as pyo3 0.20.0 was (unintentionally) not pinned against an exact patch version pyo3-build-config, and pyo3 0.20.0 could not build against pyo3-build-config 0.20.1 due to an internal API adjustment.

Thank you to the following users for the improvements:

PyO3 0.20.1

This release is a maintenance release to resolve a clippy warning which triggers on function arguments of Py<Self>.

This release also contains a few minor API additions, including optional support for the either and smallvec crates.

PyO3 0.20.0

This release is the first PyO3 release to be dual-licensed under Apache 2.0 OR MIT licensing (expanding from just Apache 2.0 of previous releases).

Python 3.12 stable is now supported. The minimum supported Rust version has been increased to Rust 1.56.

The __eq__, __ne__, __lt__, __le__, __gt__ and __ge__ magic methods are now usable in #[pymethods] to implement Python operators as an alternative to the __richcmp__ method PyO3 already offered.

#[pyclass(rename_all = "renaming_rule")] has been added to rename all fields of structs exposed to Python (e.g. rename_all = "snake_case") .
