Move base python version to 3.12

[diehlbw]

This issue is to document and track the expectation to move the base python version forward.

Currently, core testing is done in a py3.10 environment with test suite verifying stability in 3.11.
We will be moving this forward, targeting 3.12 as a baseline and starting to test in 3.13.

This is NOT removing support for either 3.10 or 3.11 (see issues: #116)

Here is what I tried and what was remaining:

• in setup.cfg, change python_requires to >=3.12
• in Dockerfile, change the first line to FROM python:3.12-slim as seismometer
• In requirements.txt, here are the changes I made that partially worked:
  • numpy>=1.26
  • numba>=0.59.0
  • scikit-learn>=1.3.1

The example notebook fully works (and is pretty snappy compared to before) but the tests fail with the following error -

ERROR tests/report/test_alerts.py - AttributeError: module 'numba' has no attribute 'generated_jit'
