Bookworm/Pi5 Compatibility: Upgrade to latest boilerplate

[Gadgetoid]

This should fix the issue with ruff reporting:

qa: commands[4]> ruff --format=github .
error: unexpected argument '--format' found

And bring a few other things - including the virtual environment helpers - up to date.

:warning: Note: the master branch will need renaming to main for badges and actions to function correctly.

The changes to io_regs.py look scary, but I used black to reformat the file and avoid any mistakes, then lined up all the comments again because I will die on that hill.

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/ioe-python -b boilerplate-update
cd ioe-python
./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.)

For the reasons behind these changes and other information, see:
