Install no longer works with python 3.12

[SanderRonde]

The configparser package bundled with python 3.12 no longer contains a SafeConfigParser export that your plugin depends on. Because of that it (along with a few other plugins) can no longer get installed on python 3.12.

The issue occurs in versioneer.py (which I'm sure you copied from the template) which contains this reference to the now-removed export. Replacing that with configparser.ConfigParser() partially solved the issue for me. After that one more pops up. On the line after a file is opened and readfp is called. readfp doesn't exist anymore. Instead, simply parser.read(setup_cfg) is enough and fixes the issue.

I think there's maybe 2 ways to fix this:

• Look at what octoprint itself did and maybe try to make that work with this plugin (see their commit)
• Just replace those two lines and wrap them in a bunch of if-not-defined-then-other-thing try-catches. Would be happy to create a PR for the latter.

This is something that is on my radar to fix for a while - all my plugins used the same template I just copied it between them.

I'll be able to look at it ASAP hopefully from mid June time - will work out the best solution.
