Add Python 3.11 support

[sastanin]

Python 3.11 was officially released on 2022-10-24, and it's the latest stable release, but it is not yet available in FlexSim 23.1:

I second this highly-upvoted feature request. It would be very useful to have additional SQL JOIN and DISTINCT functionality in Table.query().

As of 20.2, all features in this request will be supported, except for SELECT DISTINCT. SELECT DISTINCT has not been high priority because it is a redundant subset of GROUP BY. SELECT DISTINCT A, B, C FROM X is the same as SELECT A, B, C FROM X GROUP BY A, B, C.
