This release enables noisy simulation with a depolarization parameter set by the "`noise`" option, for every single gate in a circuit.

Cases of circuits with mid-circuit measurement have also been debugged.

Post v1.21.0, PyQrack offers a new optimizing "`QTensorNetwork`" "layer": this is now controlled by the Cirq simulator flag option "`is_tensor_network`."

This supports breaking changes in Cirq v1.1.

If we more aggressively `try_separate(a, b)` in the `FSim` gate, by calling `try_separate(a, b)` both before and after the gate, then SDRP might become more effective.
