crash on daemon launch with non HD screens under bookworm

[txoof]

Describe the bug rpi.gpio is no longer supported under bookworm. Need to migrate to rpi-lgpio

This can likely be resolved by updating the requirements file.

PaperPi will crash on launch with the error below.

To Reproduce Steps to reproduce the behavior: Install PaperPi under Bookworm and start it.

Hardware

• all non HD screens

related to the following issues at gpiozero: https://github.com/gpiozero/gpiozero/issues/1106 https://github.com/joan2937/lg/issues/12

This only happens when paperpi is run as a daemon; this is because the paperpi user does not have permission to create a file within the daemon environment.

[txoof]

A working directory where the paperpi daemon user can have read/write edit needs to be specified.

add the following lines to the unit file:

RuntimeDirectory=paperpi
WorkingDirectory=/run/paperpi
