Add more idaklu solver options (number 2)

[MarcBerliner]

Description

Adds more user-configurable options to the IDA solver following the list in the IDA guide.

Some code cleanup to enforce early returns.

Type of change

Please add a line in the relevant section of CHANGELOG.md to document the change (include PR #) - note reverse order of PR #s. If necessary, also add to the list of breaking changes.

• New feature (non-breaking change which adds functionality)

Key checklist:

• No style issues: $ pre-commit run (or $ nox -s pre-commit) (see CONTRIBUTING.md for how to set this up to run automatically when committing locally, in just two lines of code)
• All tests pass: $ python run-tests.py --all (or $ nox -s tests)
• The documentation builds: $ python run-tests.py --doctest (or $ nox -s doctests)

You can run integration tests, unit tests, and doctests together at once, using $ python run-tests.py --quick (or $ nox -s quick).

Further checks:

• Code is commented, particularly in hard-to-understand areas
• Tests added that prove fix is effective or that feature works

thanks @MarcBerliner, be great to have all these new options in there. I think the main todo left is to update the docstring for the idaklu solver to describe all the new options.

[MarcBerliner]

I changed IDAKLUSolver's default rtol from 1e-6 to 1e-4. This is more closely in line with other ODE/DAE solvers, such as MATLAB and Julia's DifferentialEquations of 1e-3. I've found that 1e-4 is more appropriate for solving battery systems of equations.

looks great, I'm happy with this. Thanks @MarcBerliner

Codacy still looks like false alarms, just the minor changelog issue
