After chopping up and tidying the main game loop to prevent processing callbacks ...processing while there was still coroutine logic running, it was time to tidy the Powerups Logic.

Not because Powerups really needed it, but moreso to refresh my understanding, split big classes into smaller, more focused classes, prep for new powerup logic, and introduce more bugs.

It actually went well!

Clearer classes and Godot nodes so it's easier to know where to go for new Powerup logic, added the first version of a 'rarity PWUP spawn chance' , and cut out lot's of old code & comments.

Even played a fresh new game up to level 14 before the action got too spicy for me!
