Allow scroll wheel to be used to change flying speed in creative mode and spectator mode

[stackotter]

Currently players can only fly at a single (pretty slow speed) in Delta Client. In vanilla you can use the scroll wheel to change your flying speed, which is what you should try to emulate if you work on this issue.

Scroll wheel input should already be available in PlayerInputSystem (from InputState), so you can add some input handling code to change PlayerAttributes.flyingSpeed.

This issue can only be completed once #178 is completed. At the moment, flying speed doesn't depend on PlayerAtributes.flyingSpeed.

You can access the scroll up/down inputs from InputState.newlyPressed in PlayerInputSystem (before the call to InputState.tick).

You can do that in vanilla? Since when?

I dunno, I thought since forever? I know that you can at least do it in spectator mode, and I'm pretty sure you can do it in creative mode

Just looked it up, only spectator. That explains why I'd never heard about it

Ok 👍 I had a vague memory of seeing similar logic for creative mode when I was looking at all the physics stuff in Vanilla, but I guess it's just spectator mode. I'm surprised you haven't heard of it before, it's pretty useful when searching around worlds and stuff!
