doesnt seems to work with RPi5 Bookworm 0F12.0 arch64

As for now I just try to make the simple button it compile well but the app doesn't return any result on GPIO17
I need to investigate more.

Ok so the library seems based on the linux file system tree which is not the same anymore with RPi5. Next step is to investigate on the new file system.

cat /sys/kernel/debug/gpio gives us the pinmap association:

So basically PIN3 which is GPIO2 in the RPi pinout is now accessible via GPIO401...

As low number GPIO are not used anymore it's very strange for RPi fundation to not have linked them to the new numbers... but well perhaps it'll come in a future update...
