Implemented SetBrightness function Rewritten SetBrightness function (only first idea at the moment) Use CIE1931 to modify brightness Adding new function to python bindings Fixed bug with CIE1931 lookup - Adding brightness control to python library - Adding new python sample for brightness control Fixed bug without CIE1931 correction Fixed typings
