This refactor the lightprobes sample so that we always query the spherical probe and the volume probe. Then, given the BSDF type, we reconstruct the incoming radiance differently depending on the ray probability blending between the spherical and volume probe depending on ray probability. Moreover, we implement cubemap normalization using volume probe spherical harmonic data at spherical probe position and at the shading point position.
