Remove guidata support

Follow up on jupytercad/JupyterCAD#413

@martinRenou @trungleduc Should I remove _guidata_to_options & _options_to_guidata fully or is this enough?

Also wanted to confirm that if I shall bump JCAD dependencies from 2.0.0 to 3.0.0?

I believe this is not enough. You should be able to test the colors loading when opening the file https://github.com/jupytercad/JupyterCAD-FreeCAD/blob/main/examples/ArchDetail.FCStd

Note that you need to install freecad micromamba install -c conda-forge freecad.

You need to adapt the _guidata_to_options and _options_to_guidata to read/write the colors from the FCSTD file and set the Color property you introduced in JupyterCad and the visible one.

Thanks @martinRenou, I'll be on it.

Hi, @martinRenou @trungleduc. Workflow requests approval. Plus I'm happy to have another interim look of yours :)
Thanks.
