Python 3.12 support

@thewchan here's the relevant section from the release notes.

https://docs.python.org/3.12/whatsnew/3.12.html#configparser

configparser
Several names deprecated in the configparser way back in 3.2 have been removed per gh-89336:

configparser.ParsingError no longer has a filename attribute or argument. Use the source attribute and argument instead.

configparser no longer has a SafeConfigParser class. Use the shorter ConfigParser name instead.

configparser.ConfigParser no longer has a readfp method. Use read_file() instead.

May I ask if this is still being worked on? Did #194 fix this or not? What is the problem? Does it need a new release? 1.0.0 still does not build on python 3.12

@besendorf since the owner is inactive, I've published a temporary package for 3.12 (terribly) named ssh2-python312.
