Perform WENO5-JS reconstruction on the supplied stencil.
Applies WENO5-JS reconstruction component-wise to a 5-point stencil. The stencil may be in physical or characteristic space depending on whether spatial_discretization applied characteristic projection first.
Nonlinear weight formula (Jiang & Shu 1996, Eq. 22): omega_tilde_k = d_k / (eps + beta_k)^2 omega_k = omega_tilde_k / sum(omega_tilde)
