Release of CmdStan 2.33.0

We are very happy to announce that CmdStan 2.33.0 is out!

This new release brings two new exciting features that have been in the making for more than a year: a new Stan language type - tuples and a new VI algorithm - Pathfinder. The release also features some new functions - mostly related to tuples, and other minor improvements.
