Turn CPU/GPU "hybrid" option off by default

This release (only) turns CPU/GPU "hybrid" simulation mode off by default. (The option can still be turned back on by users.)

Debug noise (weak simulation condition)

Noise requires "weak simulation condition" to work correctly. In other words, if the noise constructor parameter is greater than 0, analytical sampling must be disabled and one full circuit simulation must occur per shot. This release systematically fixes this condition within QasmSimulator.

Optional noisy simulation

QasmSimulator gains a numerical option noise that adds stochastic Pauli noise (equivalent to depolarizing noise) with a parameter setting indicated by the user-assigned value of noise (typically between 0 and 1).

Full Changelog: v0.12.0...v0.12.1

Binary measurement strings

To match the convention of Aer, the QasmSimulator now returns measurement results as padded binary strings.

Handle barrier operations

barrier operations have no logical effect, but the instruction must be handled by the backend.

Update for Qiskit v1 changes

This converts the provider to use BackendV2 and drop use of ProviderV1, per the updated Qiskit API.

"sy" and "sydg" gates

This release adds the "sy" (square root of Pauli Y) and "sydg" (adjoint of sy) gates to the Qrack simulator back end.

"Reactive separation" off by default

This release changes the "reactive separation" option to False or "off" by default.
