[Rivet] Bug/change in RIVET IdentifiedFinalState()?

[Chris Pollard]

Seems like it was only added in 2.2.1? Marco, do you have access to 2.2.1
in athena?

    * Add &&, || and ! operators for without-parens-warnings Cut

    combining. Note these don't short-circuit, but this is ok since

    Cut comparisons don't have side-effects.

    * 2.2.0 release!
