Bumps pyo3 from 0.16.3 to 0.16.4.

Release notes

Sourced from pyo3's releases.

PyO3 0.16.4

This release fixes a regression introduced in 0.16.3 leading to build failures on Windows, enables crates depending on PyO3 to collect code coverage using LLVM instrumentation on stable Rust version 1.60 or later, and enables safe access to time zone information attached to Python's time and datetime objects. There are also some adjustments to PyO3's build-time interpreter detection to make it easier to cross-compile abi3 Python extensions.

Thank you to the following users for the improvements:
