Adding PR workflow

[jacubsmith]

Description Adding workflow for when a PR is submitted to run a linting check, have done this over the pre-commit as there is a lot of errors that come up when running the linter. They are all syntax based and won't cause build errors but is another task to go through and fix them up.

This method will allow you to merge PR's anyway so development isn't halted. Once they are fixed we can add in the pre-commit hook.
