Modernize

use pyproject.toml and lock files

Modernized version of package.
Lock files should be commited to allow for easier reproduction of errors/problems.

CI for new python versions

adopted from https://github.com/samuelcolvin/rtoml/blob/a957d04c4a32de00a5901a9dd78df559b7cd901e/.github/workflows/ci.yml

fixes #16

I was so free to update the CI as well.

The new CI uses https://docs.pypi.org/trusted-publishers/
Register your project accordingly.
It is much safer as using the pypi token.

I hope the modified/copied ci run through.

Ok I tried around using the maturin in the CI but this required an update of PyO3 and chrono as it seems which is more as my current rust knowledge allows for.

I paste my WIP maybe you can work on it faster than I do?

[CarliJoy]

Ok I managed to build everything but Windows aarch64 platform (maybe we can skip it?).

I hope it is a good enough start point for you release a new version.

There are some warnings when building that might be good to fix?

Also there are some crono feature flags in pyo3 that might be good to have look at?
See https://docs.rs/pyo3/latest/pyo3/chrono/index.html

But maybe release just a new build for a new python version and optimize later?

[CarliJoy]

@gukoff could you have a look?

[gukoff]

Thanks a lot @CarliJoy, I appreciate it! I will review it in the next few days.

The microsecond parameter type has changed from u32 to the inferred type from nanosecond() / 1000. Since nanosecond() returns u32 and the division result is u32, but PyDateTime::new expects u32, this should be explicitly cast to ensure type safety: microsecond as u32.

Suggested change

	microsecond,
	microsecond as u32,

Does this line have an effect?

[CarliJoy]

I don't remember.
I think the build failed without but I am not sure.
