5th-order linear WENO reconstruction on a 5-point stencil.
Equivalent to WENO5-JS in the smooth limit: applies the optimal weights d0=1/10, d1=3/5, d2=3/10 to the three 3rd-order substencil approximations without computing beta-based nonlinear corrections. The resulting combined coefficients are:
f_hat = (1/30)v1 - (13/60)v2 + (47/60)v3 + (27/60)v4 - (3/60)*v5
See Jiang & Shu (1996), Eq. (19) combined with substencil Eq. (16a-16c).
