eMeet Pixy (328f:00c0) PTZ and HID control for Linux - reverse-engineered tracking, privacy, gesture, and audio mode commands

	#!/usr/bin/env bash
	# PTZ and mode control for eMeet Pixy webcam (USB 328f:00c0)
	# Uses v4l2-ctl for PTZ and HID for tracking/idle mode
	# Usage: cam_ptz.sh <command> [value]
	#
	# --- How the HID protocol was reverse-engineered ---
	#
	# The eMeet Pixy exposes two control interfaces:
	# 1. UVC (standard) — pan/tilt/zoom/focus via v4l2-ctl
	# 2. HID (proprietary) — tracking, audio, gesture, privacy via /dev/hidrawN
