Changes for Python 3.13 support

[monocongo]

Updates to allow for Python 3.13. Since we need the latest version of scipy which itself requires Python 3.10 we will have to drop support for 3.8 and 3.9 if this is merged.

Summary by Sourcery

Add support for Python 3.13 by updating dependencies and configuration, including scipy to version 1.14.1. Drop support for Python 3.8 and 3.9, and update CI to test against newer Python versions.

New Features:

• Add support for Python 3.13 by updating dependencies and configuration.

Enhancements:

• Update scipy dependency to version 1.14.1 to ensure compatibility with Python 3.13.
• Remove workaround for scipy bug related to Pearson3 distribution as it is no longer needed.

Build:

• Update Python version compatibility in pyproject.toml to support Python 3.10 to 3.13 and drop support for 3.8 and 3.9.

CI:

• Update CI configuration to test against Python versions 3.10, 3.11, 3.12, and 3.13.

Hey @monocongo - I've reviewed your changes - here's some feedback:

Overall Comments:

• Consider removing the obsolete pearson3_workaround code entirely since it's now permanently set to False and the minimum scipy version (1.14.1) is well above where this workaround was needed (1.6.0).

Here's what I looked at during the review

• 🟢 General issues: all looks good
