[PW41] Add MRSegmentator Model

[FJDorfner]

Pull Request to add the MRSegmentator model to mhub.

Great Work!!

I suggested some minor changes. I'll update segdb and once we have that we can continue with the test routine. Thx @FJDorfner, very clean and to the point :)

[LennyN95]

I'll add SPINE to SegDB. I can lookup the codes, but feel free to add SCT code's if you already have them ;))

[LennyN95]

@FJDorfner We're adding a quite broad label here, can you explain weather the model delineates the entire spine or the bone-structure of the spine?

[FJDorfner]

Hi @LennyN95, the model segments the bodies of the vertebrae individually. The disk between is not included in the label. This would be the yellow label in the attached Screenshot as a visual:)

• TODO @LennyN95: Add support for multi-modality inputs. Dash separation is a good idea and in line with DTQ syntax.

[LennyN95]

@FJDorfner since all comments from the previous review are now implemented, we can continue with the testing procedure.

[FJDorfner]

@LennyN95 Thanks! I will continue with the testing.

Please note, we updated our base image. All mhub dependencies are now installed in a virtual environment under /app/.venv running Python 3.11. Python, virtual environment and dependencies are now managed with uv. If required, you can create custom virtual environments, e.g., uv venv -p 3.8 .venv38 and use uv pip install -p .venv38 packge-name to install dependencies and uv run -p .venv3.8 python script.py to run a python script.

We also simplified our test routine. Sample and reference data now have to be uploaded to Zenodo and provided in a mhub.tom file at the project root. The process how to create and provide these sample data is explained in the updated testing phase article of our documentation. Under doi.org/10.5281/zenodo.13785615 we provide sample data as a reference.

Thank you @FJDorfner for fixing the issues. Looks good!
I started the testing on this PR ;)
