Use python3-libgpiod to scan /dev/gpiochip* and match each chip’s label, replacing the sysfs-only lookup. This ensures reliable detection on H616 and adds support for Orange Pi SBCs where the old method failed.

This is depending upon a specific version of GPIOD. Some versions have chip and some have Chip. It would be better to make use of https://github.com/adafruit/Adafruit_Blinka/blob/main/src/adafruit_blinka/microcontroller/generic_linux/libgpiod_chip.py which will figure out the appropriate class by looking at specific traits and returning the correct one as Chip so it's consistent.
