Standardize PyCIEMSS installation across project

[fivegrant]

Problem

PyCIEMSS was only being installed last second in the Dockerfile and lived entirely outside pyproject.toml.
Project-wide installation is now necessary though because we want to start developing tests with PyCIEMSS.

Solution

Create a new task in pyproject.toml that installs PyCIEMSS in the Docker image, local dev environment, and GH Action.

Unfortunately, PyTorch plays very poorly with Poetry so we are unable to specify it as a dependency. We instead have to pip install all of PyCIEMSS. There is a Poe the Poet task that is used to statefully install the library. Obviously, this isn't great but it's the cleanest solution available to us.

Other changes

• Removed 'extra' group
• Tests generated 'kwargs' against actual PyCIEMSS function signatures

NOTICE

PLEASE RUN A make init TO TAKE ADVANTAGE OF THIS NEW CHANGE
