Adding check for splines

[shimwell]

Description

This PR adds a check on all the imported solids to see if there are splines present. If spines are present then a VaueError is raised and a message explaining the options is provided to the users.

Here is a screen shot of a cad geometry with spines being loaded and the error message

then the cad file gets loaded again with skip_solids=[0] and the load is successful

Fixes issue

fixes #201

Checklist

• I'm making a PR from a feature branch on my fork into GEOUNED-org/GEOUNED/dev branch
• I have followed PEP8 style guide for Python or run a formatter such as black or ruff format on my code
• I have made corresponding changes to the documentation
• I have added tests that prove my fix is effective or that my feature works

I see the CI is failing with STEP files that are in the repo already. It looks like now I've added a check for splines some of the step files in testing/inputSTEP are found to contain contain splines.

I shall improve the error message so we can see which files have splines

[shimwell]

Locally I'm seeing that these files contain splines

I've replaced the code that terminated the program when finding splines with a more gentle writing to log file as it appears that spines can be contained in step files but not used and that GEOUNED is fine with this.

[shimwell]

this one is ready for review

Hey @psauvan and @jpcatalanUNED! Any idea why some of the stp files, when opened in text editor, show B_SPLINE_CURVE_WITH_KNOTS, but splines are not identified in SpaceClaim and the models translate well?

I think the STP file keeps a history of the previous edges even after they have been simplified or converted to other edge types

Check for spline by using face.surface rather than edges
