lmfit/uncertainties: 3.2.4

3.2.4 2026-January-9 Adds: Adds a section in the documentation advertising the forthcoming 4.0.0 release. Add github action CI to automatically publish a new package version to pypi when a github release of a new version is published. Increases the stacklevel of the warning about std_dev==0 so that it blames the caller rather than blaming the ufloat() function. Adjusts the Sphinx configuration to allow for reproducible builds using SOURCE_DATE_EPOCH. Mark Python 3.13 and 3.14 as officially supported. Deprecates: The AffineScalarFunc.derivatives property has been marked as deprecated. This property will be removed in a future release. The AffineScalarFunc.error_components() method has been marked as deprecated. This method will be replaced by a property of the same name in a future release. Support for interoperability between uncertainties AffineScalarFunc scalar objects and np.matrix objects is now marked as deprecated. According to the numpy documentation <https://numpy.org/doc/stable/reference/generated/numpy.matrix.html>_ usage of the np.matrix class is no longer recommended.
