build(rust): Bump up numpy and pyo3 to 0.28

[florianvazelle]

Hi 👋

I submit this PR to bump pyo3 and numpy dependencies from 0.27 to 0.28.

pyo3 deprecates the automatic implementation of FromPyObject for Clone pyclasses, so I tried to preserve the current behavior (this is the main change made).

Feedback and suggestions are very welcome 🙂

Does the test suite pass if we skip the FromPyObject implementation for all our pyclasses? I honestly don't see why we'd want any implicit FromPyObject implementations.

[florianvazelle]

Hi @orlp, if we skip the FromPyObject implementation for some pyclasses, the crate don't build.

It's seems to implicitly implement the trait pyo3::impl_::pyclass::ExtractPyClassWithClone that is required for some pyclasses, to implement pyo3::FromPyObject<'_, '_>.
This allow to call PyDataFrame::extract (or pydf.extract::<PyDataFrame>) for example.

[orlp]

Could you do one more pass over everything, aggressively removing from_py_object in favor of the skip, unless it really doesn't compile without?

[florianvazelle]

Yes, that's how I proceeded initially

pyclasses with the from_py_object: PyLazyFrame, PyOptFlags, PySeries, PySampler, PyCategories, PyDataFrame, PyDataTypeExpr, PyExpr, PySelector
And pyclasses with the skip_from_py_object: PyWhen, PyThen, PyChainedWhen, PyChainedThen, PyOperator, PyStringFunction, PyBooleanFunction, PyTemporalFunction, PyStructFunction, PyFileOptions, PyInProcessQuery, PyExprIR, PySQLContext
