Migrate code and build library

[kratman]

Goals:

• Basic tests of the import
• Build locally and CI
• Remove anything unneeded from build system
• First pypi release (needed to remove IDAKLU source from pybamm)

Before review/merge:

• Sync C/C++ code with PyBaMM

Progress

Building:

• Nox (local and CI)
• Linux wheels
• Mac wheels
• Windows wheels

Tested:

• Mac install from wheels
• Module import
• PyBaMM functionality

Releasing:

• Trusted publisher setup for pypi

Not covered in this workpackage:

• Configure pre-commit
• Using a build system other than nox/setuptools
• IREE builds

I have a temporary fix for the linking to casadi, I will replace this as I wrap up the PR

C++ code is synced as of pybamm-team/PyBaMM@62a7ee8

@MarcBerliner Can you check this branch out and make sure it works locally for you?

Commands:

virtualenv .venv
source .venv/bin/activate
pip install nox
nox

This will trigger a single unit test that just checks if the idaklu module is importable.

Wheels for stand alone tests can be found here.

I also made a branch for removing idaklu from pybamm. I am not going to make a PR for it until pybammsolvers is on pypi so that the CI won't work until the release is done. The branch is here. Since the release is not available yet, you have to install the wheel first.

virtualenv .venv
source .venv/bin/activate
pip install pybammsolvers-0.0.1-<your_arch>.whl
pip install "[.all,dev]"
