Pyqrack

Qrack's optimized "arithmetic logic unit" has been wrapped for PyQrack.

Some errata: This might be not the exact build that went to PyPi, for 0.3.0. However, after accidentally publishing a transient artifact, I tested that build for 2 known (negative) issues, and found that neither were issues for the version on PyPi:

1. `mtrx` custom gates should be cast to floats, when broken into real and imaginary components from complex numbers. (This would raise a warning in SimulaQron tests, if not fixed in the package, but the package does not raise this warning.)
2. Qrack binaries should have been updated to actually contain the ALU method wrappers. (The package correctly runs Grover's search on a lookup table, so its binaries must contain these methods. I only generated one new set of binaries.)

There was a change to the README that I wanted to include, but it isn't critical. The labor-intensive part of any PyQrack release is building all Qrack binaries, which are already built correctly for 0.3.x release, so, if an issue arises, It'll take 15 minutes to iterate a patch. Please continue to feel free to open issue tickets.

This adds the Schmidt decomposition methods `Compose()`, `Decompose()`, and `Dispose()` to this **alpha version** release.

This **alpha release version** allows the user to specify any location from which to load the **vm6502q/qrack** compiled libraries, by setting the environment variable `PYQRACK_SHARED_LIB_PATH`.

This fixes the Mac build, bumping **alpha release** v0.1.0 and v0.1.1.

This fixes the Windows build, to bump **alpha version** v0.1.0

This is the first **alpha** version release of **PyQrack**. It includes **vm6502q/qrack** shared libraries and static libraries. **For much more control over the package options, we suggest that advanced users build qrack and pyqrack from source,** but this package represents the most commonly demanded build configuration.
