At times step-files containing DEGENERATE_TOROIDAL_SURFACES fail to mesh properly

Using some CAD-tools (e.g. onshape) it is possible to choose to "export to step" with the convert surfaces to b-surfaces feature enabled. This can act as a workaround for this problem.

The problem has been reported upstream to OpenCASCADE. Closing for now as solutions have to be upstream.
