BRDF viewing/illumination angle configurations

Predefined sets of solar/viewing zenith and relative azimuth angles used to compute the bidirectional reflectance distribution function (BRDF) of the canopy. brdf_angles_no_oversampling omits the finer angular oversampling used by brdf_angles/brdf_angles2.
