LaurieGale10/primmdebug: v1.3.0

PRIMMDebug has finally been updated after results from a classroom study! More to come, but here's the main ones: Forced articulation (having to write responses to each PRIMMDebug stage) is gone (apart from in Fix the Error). It's still encouraged, but optional. You can now skip to the Find the Error stage. You now have to change the program (and write a response) to move from Fix the Error to Test. Change enter for button pressing behaviour (now have to press control+return) Full Changelog: https://github.com/LaurieGale10/primmdebug/compare/v1.2.1...v1.3.0
