Remove Python 3.13 version cap on lgpio dependency - #1107

- Change lgpio requirement from 'lgpio;python_version<"3.13"' to 'lgpio>=0.2.2.0' so it installs on Python 3.13+ - Pin >=0.2.2.0 to avoid the broken empty stub (0.0.0.2) on piwheels - Remove unused yellow_text() function and raspberry_pi variable that were only used for the now-removed manual install warning - Remove post-install warning about manual lgpio installation The version cap was preventing lgpio from being installed on Python 3.13+ which broke GPIO on Raspberry Pi 5. The lgpio dependency is only included when running on Raspberry Pi hardware (checked via /proc/device-tree/compatible). Pre-built aarch64 wheels for Python 3.13 and 3.14 are available at: https://github.com/adafruit/lgpio-python-wheels Fixes adafruit#1016

Looks good and makes sense.

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.

Problem
setup.pypinned lgpio topython_version<'3.13', which meantpip install adafruit-blinkaon Python 3.13+ would skip lgpio entirely, breaking GPIO on Raspberry Pi 5.On 3.13, the post-install message told users to install lgpio manually, but the upstream source tarball fails to build without
swigandliblgpio— so most users hit a dead end.Fixes #1016

/proc/device-tree/compatiblecheck), so this has no effect on non-Pi platforms.Pre-built wheels
Since there are no aarch64 lgpio wheels on PyPI, pre-built statically linked wheels for Python 3.13 and 3.14 are now available at:
