* Should reduce concurrent burden at the expense of time. Code is required to lint before running. This will help us during hackathons etc when there is a high burden on the GHA runners, but will be slower in general use.

 - linting and testing in one GHA file
 - Linting is required to pass before pytest or nf-test runs
 - Check for changes only happens once
