When installing on a Raspberry Pi and lgpio is not already available, print guidance directing users to either: - Install via apt: sudo apt-get install -y python3-lgpio - Use pre-built wheels from adafruit/lgpio-python-wheels This helps users who encounter build failures when pip tries to compile lgpio from source without swig and other build dependencies. Follow-up to adafruit#1107

When installing Blinka on a Raspberry Pi where lgpio is not already available, this prints a helpful message directing users to either:
sudo apt-get install -y python3-lgpioWithout this, users in a clean venv (no
--system-site-packages) would see a cryptic swig build failure when pip tries to compile lgpio from the source tarball.The lgpio dependency is still listed in
install_requires, so pip will still attempt to resolve it — this just ensures users get clear guidance on the easy fix if it's not already installed.
