some more work on mlx90640 sensor. i have it working using only 64 bytes of buffer, the same level as amg8833. the mlx90640 sensor has built in ram so i read just 32 words at a time, include a 10ms delay after serial data sends to make sure serial buffer is clear, and i2c data line works error free. (this can be tweeked later so that no serial data is sent while i2c is working, i plan to next get this data to be displayed thru the sp77xx display i have in spi mode, and then submit it as example code. this still does not have calibration data and just assumes the similar offsets from the first row, this seems about correct for now. not yet code ready for accurate sensor temps, but can be example code showing people how to use the sensor

mlx90640 sensor full read example made for uno controller. uses all 768 sensors to display 5 levels of data
