HT-203U: reconstructing thermal camera capture on Linux

HT-203U Linux tools reconstruct video and temperature capture for the HT-203U USB thermal camera. Protocol notes document its UVC frame layout, USB control sequence and calibrated mode 8 temperature encoding; the supplied scripts display live video, read summaries and save per-pixel temperature frames.
