Calculates surface reflectance from top of atmosphere radiance using the model developed by Tasumi et al. (2008) and Allen et al. (2007), which considers a band-by-band basis.

"L7" for Landsat 7, "L8" for Landsat 8 or "auto" to guess from filenames
area of interest to crop images, if waterOptions("autoAoi") == TRUE will look for any object called aoi on .GlobalEnv
solar incidence angle, considering plain surface
