Bump pyo3 from 0.11.1 to 0.12.4

[dependabot]

Bumps pyo3 from 0.11.1 to 0.12.4.

Release notes

Sourced from pyo3's releases.

PyO3 0.12.4

This release fixes a reference count issue discovered in PyO3 0.12.3, present in the implementation of From<Py<T>> for PyObject. Usage of this implementation would lead to an incorrect Python reference count decrease, likely leading to use-after-free.

This regression was only present in the PyO3 0.12 series. The offending implementation was used only in one location inside the PyO3 codebase itself, though of course is likely used in downstream code. As a result, previous PyO3 versions in the 0.12 series will be yanked.

Sincerest apologies for the inconvenience.

Fixed

• Fix reference count bug in implementation of From<Py<T>> for PyObject, a regression introduced in PyO3 0.12. #1297

PyO3 0.12.3

This release fixes support for Rust versions 1.39 through Rust 1.44, which was erroneously broken in PyO3 0.12.2. Thanks to @mtreinish for the quick bug report!

PyO3 0.12.2

This release adds the ability to specify keyword-only arguments in #[pyfunction] definitions, a new function Python::check_signals, and a couple of smaller refinements improving upon PyO3 0.12.1.

Thank you to everyone who contributed code, documentation fixes, design ideas, bug reports, and feedback. The following users' commits are included in this release:

@birkenfeld @davidhewitt @dvermd
@kngwyu @sebpuetz

PyO3 0.12.1

This release contains a couple of bugfixes to resolve complation issues with 0.12.0 on specific targets. Thank you to @alex and @mtreinish for the bug reports and subsequent patches.

Fixed

• Fix building for a 32-bit Python on 64-bit Windows with a 64-bit Rust toolchain. #1179
• Fix building on platforms where c_char is u8. #1182

PyO3 0.12.0

This release includes a few careful revisions to the PyO3 API with the intention to make it easier to learn and use. The PyErr type is reworked to implement std::error::Error. The FromPy trait is removed. Finally, the PyObject struct is now just a type alias to Py<PyAny>. While we do not take pleasure in making breaking changes for users' code, we have done so with careful thought to make migration as simple as possible while also allowing the PyO3 API to mature. Please see the migration guide for help upgrading if any of these changes affect you.

Also added is a new #[derive(FromPyObject)] macro, which enables a convenient way to accept arguments of the Python "type" Union. (See the guide entry on this new feature.)

There have been many other improvements and bugfixes too numerous to go into detail here. For the full list, see the CHANGELOG.

Thank you to everyone who contributed code, documentation fixes, design ideas, bug reports, and feedback on the way to PyO3 0.12. The full list of users who commited at least one contribution to PyO3 0.12 is below:
