 +  * Color Grading "bulk" API (a single table's load time is reduced 10x, from 0.023 to 0.002s along with replacing 193 separate USB calls with a single one!)
 +  * fixed 4K@30fps NV12 video streaming
 +  * (final?) massive code refactoring
 +  * start FPGA in "off" mode until a request for a video stream comes in (keep the device a bit cooler!)

   * bugfix - there was a regression in ''53'' that caused FPS to be lower than expected as a result of UVC's probe-control negotiation caused by incorrect USB speed values (by mistake a USB 2.0 speed was used for USB 3 calculations!)   * bugfix - there was a regression in ''53'' that caused FPS to be lower than expected as a result of UVC's probe-control negotiation caused by incorrect USB speed values (by mistake a USB 2.0 speed was used for USB 3 calculations!)
