Installer does not use the most recent release

[AmadeusW]

I followed instructions to install explorer-hat on a fresh raspi image (Bullseye version, kernel 5.10.92-v7+)

At runtime, it failed with AttributeError: 'AsyncWorker' object has no attribute 'isAlive' which has been fixed in #50

It looks like the default installation does not use version 0.5.1. explorerhat is already installed (v0.4.2) and therefore it's not updated. Perhaps it would make sense to add a flag to the installer to force an upgrade?

I fixed this with pip install --force-reinstall explorerhat==0.5.1 which upgraded explorerhat-0.5.1 and cap1xxx-0.1.4

pip install --upgrade explorerhat should also work, but you're right- this is an oversight and I think it applies to all of our installer scripts 😬

Updated the README to clarify this, and also updated the installer to use --upgrade so that it fetches the latest version if there's one already installed.

This should also be updated on the PyPI description, it is still pointing users to the apt-get installer which installs an older version.
