Further refine autoreload
This unifies the delay into the post-run delay that also waits for user input and fake sleep. This ensures we always delay. Previous code would only delay if the code.py was running when autoreload was triggered. Now it will always delay. We also now suspend autoreload when a USB write starts and then resume on completion. This should prevent reloading in between sectors of a single write.
