Rework settings and update to IfcOpenShell v0.8

[hlg]

There have been changes to the way how IfcOpenShell handles settings from v0.8 on. The rework might also consider new settings such as "permissive extrusions" (allows extrusions depths of zero or less). Parallel adjustments might need to be made on the geometry server side in IfcOpenShell itself.

See https://github.com/IfcOpenShell/IfcOpenShell/issues/1490#issuecomment-2306598309 for reference.

Maybe the settings could also be handled dynamically, but then it needs some thought how compatibilty between versions is going to be handled and how settings should be maintained in the BIMserver database while allowing for the IfcOpenShell version to be switched.
