Description
Add two-qubit Pauli product gate decomposition and id gate mapping. Add catch-all error to gracefully error if Stim doesn't know. Fix setToZeroState to reset simulators in place instead of deallocating to allow multiple calls.
For the most part these conditions are not reachable from the standard gateset that is exposed. However, this downstream enables PTSBE support when combined with #3934 for most gatesets. It also should also now provide a more graceful error when operations are not supported.
