Adds uniaxial compression validation for the 2D cantilever beam
(fully clamped left edge, traction load on the right edge), plane
stress. Same setup as the plane strain counterpart (PR: 2d-compressionDP),
beam2d_tri.msh, L=1, H=0.2)on the right edge via consistent nodal forces
template="Vec2d"lambda = E*nu/(1-nu^2)` on the FreeFEM side)
