[Suggestion] Curve the npeghole primitives

[Max Murtazin]

Is it that much significant, tho? Modern PCs (something from last 5-6 years) can easily handle pretty extreme polygon counts. Polygon number increase from this for sure will be big, but not exponential. Not something that is a real game changer to make new version of primitives impossible to use. Axle primitives got updated not so long ago, and polygon increase was way more dramatic for those, than what is necessary to have smooth npegholes
