Crash processing IIfcExtrudedAreaSolid - Possible solution

[r-silveira]

I have a model that crashes when processing IIfcExtrudedAreaSolid.
After doing some tests, it seems to be a numerical precision issue. If I change the values ​​(like exporting using another tool) the model opens.

IFC excerpt with this issue:

I made a fix for this, ignoring the invalid faces. I'll submit the PR.

I used this test model with the version Xbim Geometry v5.1.762-develop:
