ImpressionFEA 0.7.1: robust 2D fold recovery

ImpressionFEA 0.7.1: more robust 2D solver at die fillets and in thin flash.

• No more "element folded" stops near closure. When the die contact lays every node of a boundary element on
  the die (a corner filling at a fillet, or the last flash-thinning increment), no step cutback can avoid the fold.
  The 2D solver now accepts that update and remeshes the workpiece on its new outline instead of stopping.
• Fixed "stiffness matrix not positive definite" after a remesh in axisymmetric jobs: volume compensation could
  push a surface node near the axis to a negative radius.
• Demo 3 (flanged shaft, 6061 at 450 °C) now forges to closure with 1.0, 1.25 and 1.5 mm meshes at every ram speed.
