CircuitSimulator Refactor

[amccaskey]

Add applyGate method for subclasses to implement instead of requiring overloads for all gate methods.

Introduce gate queue to better support mid-circuit measurement and data persistence to named classical registers.

Introduce unique cached circuit name to support sub-type caching strategies (e.g. cache the optimal contraction path for a given circuit).

Break up the python quake file check tests into separate ones for easier debugging.

I like the refactoring, it does simplifies the code. However, it seems that the set of changes is orthogonal; They could have been broken into smaller, more focused PRs (might still be worth doing it).

Breaking up the big python test into smaller ones is a great move, but I would still keep similar ones on the same file, specifically leaving all qalloc tests in the same file.

The fix in the clang-format configuration file is likely to affect the whole code base, it certainly worth creating a separate PR that with the fix and rerun in the entire codebase.

LGTM, thanks for this work Alex!
