Bookworm/Pi5 Compatibility: Upgrade to latest boilerplate, port to gpiod

[Gadgetoid]

Testing

If you're a Bookworm / Pi 5 user running into virtual environment issues, you can try this library like so:

git clone https://github.com/pimoroni/cap1xxx -b repackage
cd cap1xxx
./install.sh --unstable

The ./install.sh script will create a pimoroni virtual environment that's shared between our products. (or use your existing venv if you've already activated one.)

Tested with:

• Explorer HAT Pro
• Drum HAT
• Piano HAT
• Touch pHAT
