OpenNest/OpenNest.Tests/Splitting/TestData/split_test.dxf
AJ Isaacs 6880dee489 fix(splitter): preserve disconnected strips and trim cuts around cutouts 
Splits that cross an interior cutout previously merged physically
disconnected strips into one drawing and drew cut lines through the hole.
The region boundary now spans full feature-edge extents (trimmed against
cutout polygons) and line entities are Liang-Barsky clipped, so multi-split
edges work. Arcs are properly clipped at region boundaries via iterative
split-at-intersection so circles that straddle a split contribute to both
sides. AssemblePieces groups a region's entities into connected closed
loops and nests holes by bbox-pre-check + vertex-in-polygon containment,
so one region can emit multiple drawings when a cutout fully spans it.
