mid-circuit measurement can be interleaved with other gates, should first call tc.translation._merge_extra_qir to get an ordered set of gates and measurements

@refraction-ray added this functionality and code works thanks
Merge extra QIR with the main QIR to get an ordered set of gates and measurements
```merged_qir = tc.translation._merge_extra_qir(tc_circuit._qir, tc_circuit._extra_qir)```

please also compare the results with baseline results by tc.quantum.entanglement_entropy, also one needs one extra argument for entanglement calculation -- the sites to be traced

@refraction-ray compared it with baseline entropy here is the result

@refraction-ray Hi Github is not allowing me to make changes in the same PR |
This PR introduces support for mid-circuit measurements and entanglement entropy computation in the tensorcircuit library. Mid-circuit measurements are a crucial feature in quantum circuit simulation, allowing for measurements to be performed at intermediate stages of circuit execution. Additionally, entanglement entropy computation provides valuable insights into the entanglement properties of quantum states, aiding in quantum error correction and algorithm development.
Key Changes:
Mid-Circuit Measurement Support:
Implemented functionality to support mid-circuit measurements in the tensorcircuit library.
Introduced a new method M to perform mid-circuit measurements on qubits.
Entanglement Entropy Computation:
Added a function compute_entanglement_entropy to compute the entanglement entropy from the stabilizer tableau extracted after circuit execution.
The function constructs a binary matrix representing the stabilizer tableau and computes its rank to determine the entanglement entropy.
