[ways]

Description

This closes #130 by adding more metadata to checkpoints.

What problem does this change solve?

Add more info to checkpoint metadata about modules used in training. The URL, subdirectory and more.

What issue or task does this change relate to?

#130

Additional notes

If someone is parsing the metadata already, this could be a breaking change, but I don't think it is.

Old metadata:

"anemoi.models": "0.12.0",
New metadata:

            "anemoi.models": {
                "source": {
                    "subdirectory": "models",
                    "url": "https://github.com/ways/anemoi-core.git",
                    "vcs_info": {
                        "commit_id": "5abd0c8f3f05cb949800c8bb4878a29312c0e0aa",
                        "requested_revision": "models-0.12.0",
                        "vcs": "git"
                    }
                },
                "version": "0.12.0"
            },

Tested like this:

• Check out https://github.com/metno/bris-inference
• Edit tox.ini test named "training"
• change deps to:

deps =
    anemoi-training@git+https://github.com/ecmwf/[email protected]\#egg=pkg&subdirectory=training
    anemoi-graphs@git+https://github.com/ecmwf/[email protected]\#egg=pkg&subdirectory=graphs
    anemoi-models@git+https://github.com/ways/[email protected]\#egg=pkg&subdirectory=models
    trimesh

• change commands_pre = to:

commands_pre =
    # Copy config file to the temp directory.
    cp -vf {toxinidir}/config/tox_test_train.yaml {envtmpdir}/
    # Link training data
    ln -sf {toxworkdir}/bris_random_data.zarr {envtmpdir}/
    pip install 'anemoi-utils@git+https://github.com/ways/anemoi-utils.git@larstest'

• run test uv tool run tox -e training
• Look at checkpoint produced: uv tool run anemoi-utils metadata --dump .tox/training/tmp/training-output/checkpoint/*/inference-last.ckpt
• Optional: compare with checkpoint produced with existing anemoi-utils, anemoi-utils == v0.4.43

Rather than alternate between dict and str, I think just a dict of {'version':version} would be better.

Seems like a very broad exception catch
