[dependabot]

Updates the requirements on pyo3 to permit the latest version.

Release notes

Sourced from pyo3's releases.

PyO3 0.18.3

This release fixes an issue with PyDateTime::type_object() incorrectly returning the type object for PyDate, which would cause some is_instance checks to behave incorrectly.

In addition, this release contains a handful of minor quality-of-life corrections over PyO3 0.18.2.

Thank you to the following users for the improvements:
