Add Python 3.13 and 3.14

[remlapmot]

Hi Ryan

I had a look at this.

Great work.

As far as I can see the tests also pass under Python 3.13 and 3.14, so I see no reason not to add them into the project - unless you know of a reason.

Also I added the dev dependency-group to the pyproject.toml with pytest, black, isort, and the packages for the docs site (so those packages get installed when one runs uv sync).

You can test under different versions of Python quite quickly with uv virtual envs as follows:

uv venv --python 3.13
source .venv/bin/activate
uv sync
uv run pytest
deactivate

(I got one tiny warning about one of the dependency packages under Python 3.14 - but that's for that package to fix.)

(And I had to add pytest.approx() to the parallel test - but obvs not reasonable to expect different architectures to be equal down to like 10 d.p.)

cheers
Tom

P.S. Not sure if I am meant to bump the version in pyproject.toml or not.

This looks good to me - thanks for checking additional python versions.

Since this is just tests and config files, and we aren't planning to push to pypi, perhaps we hold off on bumping the version. If you want to initiate an update to pypi, I think it requires a different version

thanks - that's very helpful info about the version number - I won't bump it
