back out of fast bullet changes, keep optimizations
in the "nothing but turrets" worst-case scenario, fast bullet logic costs 133% of slow bullet logic even when almost all shots on screen are slow. when I back out of this, that scenario is _still_ over 300% CPU but at least it's not 400%. note that this is with a screen mostly full of enemies, so processing all of them and their potential collisions also has cost, so the actual bullet-specific change is closer to 150%, maybe 200%. this is genuinely not as bad as I had thought but it doesn't feel like it will be workable; while my worst-case scenario is implausibly bad it's not actually 3x-likely-peak bad. so I'm going to need to find more optimizations, and probably give up on fast bullets. But I can keep the fast bullet branch around in case I find the headroom to reintroduce it later.
