convert circuit to detector error model

[Krastanov]

We can already convert a code or a parity check tableau into a faults matrix or a tanner graph. But generalizations of the tanner graph to things like stim/pymatching's "detector error model" would be quite neat too

Detector appears to be under the heading of Annotations. There is a comprehensive writeup on DETECTOR here.

Maybe the following are of interest as well w.r.t [Ref]:

• [ ] Noise Channels: DEPOLARIZE, HERALDED, CORRELATED ERROR, etc.
• [ ] Collapsing gates: RX, RY, RZ, R
• [ ] Generalized Pauli Product gates: MPP, SPP, SPP_DAG, CPP(not merged yet)
• [ ] Annotations: Includes DETECTOR
• [ ] Control Flow: REPEAT

For Single Qubit Gates w.r.t stim, all the rest that were not present were all completed in PR 333. About Two Qubit Gates w.r.t stim, most of them that were not present were all completed in PR 336. So, only 4 of these gates remain after 336, working on a PR towards it as well.
