5.0.0 Beta 1

This is a beta release for the upcoming 5.0 that drops Python 2 and adds Python 3.12

Source and wheels for 5.0.0b1 is available on PyPI.

This beta restores fast_executemany, so it should be feature complete. If there are no serious issues reported, it will be released as 5.0.0 this week (before Python 3.12 is officially released).
