Future proofing package

[veenstrajelmer]

What is the need for this task.
There is lack of official documentation (like classifiers) about which python versions are supported and to my knowledge no py3.13 and numpy 2 tests are executed yet.

What is the task?

• update readme badges #178
• check if all tests succeed with numpy 2.0, fix in case of failure. >> both numpy>=1.22 (as currently) and numpy 2.* should be supported. Teamcity tests with numpy 2.1.2, so this is supported.
• add mydeltares as pypi maintainer
• add supported python versions (should at least be 3.9 to 3.12) as classifiers, at least make sure these are available on pypi
• run teamcity tests for other versions than python 3.10 only, at least also the first and the latest supported version (e.g. 3.9 and 3.13), since these will likely result in different versions of dependencies.
• check support for python 3.13 (and add to supported versions), requires python 3.13.1 because of win 10 Python-3.13.0 tkinter fails in venv python/cpython#125235
• move from setup.py to pyproject.toml
• single source of truth for dependencies, so remove requirements.txt. Use pip install -e . instead or if you only want the dependencies consider toml-to-requirements
