bm.verts.new to new_verts

Слиты nikitronn запросил слияние github/fork/vicdoval/sv_bmesh_utils_performance в master

Created by: vicdoval

as stated here https://github.com/nortikin/sverchok/issues/2767#issuecomment-588979117 this is 10-20% faster

new_vert = bm.verts.new
[new_vert(v) for v in verts]

than this [bm.verts.new for v in verts] the same logic applies to bm.faces.new and bm.edges.new

  • Ready for merge.
