Pyqrack

This release fixes a bug in the underlying `Qrack::QUnit::AntiCZ()` gate method, which might have caused issues with correctness of sampling statistics, depending on how the gate was engaged.

This binary(-only) update greatly improves the efficiency of measurement sampling in cases, such as particularly when collecting a single sample with `measure_shots()`.

Measurement sampling execution speed has been greatly improved, for low-entanglement systems with Schmidt decomposition layer, and for hybrid-stabilizer layer. (The API has not changed.)

QrackSimulator()` constructor arguments have been fixed. `ctypes` does not necessarily complain or throw exception if a bound method signature doesn't correspond to that of a Python call, and this led me to originally call the wrong initialization method for specifying layer options.

Two bugs were fixed in the Qrack static and shared libraries:
- PhaseParity() gate gave incorrect results, depending on optimization layers, in the static library
- Boolean gates in the shared library did not correctly map simulator qubit labels

Additionally, importing `setuptools` instead of `distutils.core` in the `none-any` wheel seems to fix its compatibility with Mac systems, and probably more generally.

The shared library was accidentally holding onto potentially significant garbage due to unnecessary use of strong `shared_ptr` references as map keys. Stability has been improved in situations where many simulators are allocated and freed.
