Screw it! Too many keybinds - Keybind Wheel

Screw it, Too Many Keybinds (KeyWheel)
1.0.3 - the big redesign

The wheel got a proper makeover, and slots can finally wear icons.

THE NEW WHEEL
- Redesigned from floating boxes into a real segmented ring with a clear centre hub,
  the way the mod's logo always looked.
- A bright green highlight lights up the slot your cursor is pointing at, so where you
  are aiming is never in doubt.

ICONS (the headline feature)
- Every slot can now wear an item or block icon. Open a slot in edit mode and hit
  "Choose icon..." to open a searchable grid of every item in the game (FTB-Quests
  style), type to filter, click to set it. "No icon" clears it.
- Each PAGE can have its own icon too, shown in the centre hub, so you can tell your
  wheels apart at a glance. Set it with the "Page icon" button in edit mode.

READABILITY
- When a wheel has a lot of slots, the labels now rotate to run along their spoke
  instead of getting squished, so they stay readable. The centre hub always shows the
  full name of the slot you are pointing at as a backstop.
- The background dim is lighter, so you can still see the world behind the wheel.

EVERYTHING ELSE
- Pages, the keybind picker, custom slot names, dynamic slot counts, and run-as-you-aim
  movement all work as before. Your existing keywheel.json carries over.

Available for: NeoForge 1.21.1 and 1.21.8, and Forge 1.21.1, 1.20.1, 1.19.2, 1.18.2,
and 1.16.5. Client-side only, no dependencies.

Note: on MC 1.21.8 the wheel is drawn through Minecraft's new GUI render pipeline; it
looks the same, just built a little differently under the hood.
