Unexpected file in test_packages

[coreyostrove]

This is primarily a question for @enielse. I'm working through some changes in test_packages and noticed an unexpected file in test_packages\drivers called nqubitconstruction.py. This isn't a test module, but rather looks to me like it might be an early/outdated version of the cloud noise model code. I suspect this is probably from when you were originally testing that code and it probably slipped into a commit by accident, and therefore can be safely deleted. But I wanted to run that by you first before I did so. It might also be worth having you take a look to make sure there aren't any functions or code within that ought to be preserved before we remove it entirely. Thoughts?

This looks fine to remove to me. The code in nqubitconstruction.py has been incorporated into pygsti proper. I believe earlier on this file was used by the unit tests but since adding functionality to the cloud crosstalk models this is no longer needed.

Thanks @enielse! I've removed this file in my bugfix-release-0.9.12.1 branch which I plan to use as a catchall for several of the smaller bugfixes for the next release.
