[feat] drawing optimisation
add some generator to test the optoimisation: adjust_brightness.py: set some rectangle to rerify the consant of brightnes keyborad_input.py: is an exenmple of non blocking input reading angleInteractive.py: is an interactiv version to test the angle. you can separatly set the lenght of each segment you can set the angle it must be run without brightnes optimization because mey be lenght have an importance
