Add apply_overrides

[barneydobson]

Addresses: #67

Edit:

Going to go with @dalonsoa 's initial suggestion - implicit in this is that parameters are not override-able by default. The more I looked the more I realised that most parameters we probably don't want to be override-able.

@dalonsoa I guess not too much here to cause trouble. I don't quite get the failing ruff stuff- since it says maybe it can fix automatically? Is it working differently than pip_tools_template and not automatically doing this at commit?

[dalonsoa]

It should be doing the very same thing in the CI and in your local copy when making a commit. I guess you have, but just checking: is pre-commit installed and running whenever there's a new commit?

[barneydobson]

Yes it was that - I was using an old wsimod environment

Looks good to me as the starting point!

The QA is still failing. Follow the suggestions in the errors and force the run of pre-commit in all files. Let's see if that fixes the issue.
