Extract centerline may crash slicer on tight arterial stenosis

[lassoan (Andras Lasso)]

Probably this fix solved this problem:

Extract centeline Auto-detect tree mode

The crash was due to a bug in VTK that I’ve fixed a couple of months ago, but that fix was not yet backported into Slicer’s VTK. I’ve now backported it, so centerline extraction will work robustly in Slicer Preview Release that you download on 2023-03-19 or later.
