A size checker action which checks for files > 100KB.

If any files being added or changed by a pull request are larger in size than 100KB this test will fail, raising an error that lists files that exceed this threshold size. A warning annotation will be added for files that exceed 50KB.

This was tested using files that have been removed from the history to avoid swelling the repository size. First the annotation when a file exceeds 50KB.

And with two files that exceed 50KB:

And with an additional file that exceeds the hard limit of 100KB:

@cpelley this is perhaps a little clumsy and the test should be put into a script file. Very open to suggestions as this is my first foray into github actions.

Hey Ben. Gosh I didn't think you would get to this so quickly!
I would suggest that instead we utilise the check-added-large-files pre-commit check which stops large files from being committed at all. The github actions can then also run the pre-commit checks (as done in improver_suite).

improver_suite is a suitable reference for how pre-commits are setup and how they are also run via github actions. I can put together a PR targeting your branch if you prefer?

I should say, we can go with your approach first and do the pre-commit later, since you have done the work already.
Up to you. What you think?
