Python 3.12 works

[sorenwacker]

Hi ISA-tools team,

I've been working on a fork that adds Python 3.9-3.12 compatibility to isa-api. The changes include:

• Updated dependencies for Python 3.9-3.12 support
• Fixed pandas deprecation warnings (.replace() → .map(), added .infer_objects())
• Fixed SQLAlchemy 2.0 compatibility in database models
• Updated GitHub Actions CI workflow
• Added flake8 configuration for SQLAlchemy forward references

The fork is available at: https://github.com/sorenwacker/isa-api/tree/python-3.12

All tests pass on Python 3.9-3.12. If you're interested in merging these changes upstream, I'm happy to create a PR. Otherwise, feel free to use this as a reference if/when you decide to update Python version support.

Disclaimer: These changes were made with assistance from Claude Code (Anthropic's AI coding assistant).

Best regards
Soren
