Rust code

[ciaranra]

Including Rust code for stabilizer simulator.

TODO:

• Have CI workflow that checks Rust tests and formatting
• Update Makefiles to build etc. both Rust and Python projects given restructuring
• Have CI workflow that builds and install pecos-rslib and tests pecos-rslib
• Have CI workflow that tests the usage of pecos-rslib from Python PECOS
• Add PyO3 wrapping for Rust simulators and make available to Python via pecos-rslib
• Update tests to test Rust simulators used in Python PECOS
• Add RSSparseSim to Python test_random_circuits (likely need to add force_outcome measurement)
• Add Rust tests for the newly added gates for the Rust stabilizer sim
• Update/modify various Readmes as appropriate...
• Use symlinks to point to the appropriate legal and Readme stuff
• Have CI workflow that is generates sdists and wheels for all the Python packages
• Add version consistency checks for Python packages and Rust crates
• Update workflow to save artifacts only on success merges, direct pushes, or py- tags in main branches
• Update README.md if needed

Mostly just tried to work through the development section of the README.

make test-all gave me:

======== short test summary info ========
FAILED docs/api_guide/circuit_runners.rst::circuit_runners.rst

======== 7 failed, 2 passed, 1 warning in 0.82s ========

This should be resolved now. Just removing doc tests for now.

Alright, @qartik & @peter-campora. I have updated the makefile to make the .venv more of a "first class citizen" and updated the README appropriately (hopefully). Let me know if you still have issues.

I still need to figure out what is going on with this:

-pecos-rslib==0.6.0.dev6
+pecos-rslib==version = 0.6.0.dev6
