Make sure to follow the codebase's styling. Don't put a space between the class and the constructor arguments

You're gonna have to add a FormatterSettings that has all of its category hidden except the number formatting for this. Refer to the Coordinate hud module and the Formatting object to serialize tuples correctly.

@Jalvaviel here's what I had in mind.

	private val formatter = FormatterSettings(this).apply {
		applyEdits {
			::timeFormat.edit { hide() }
		}
	}

	override fun ImGuiBuilder.buildLayout() {
		runSafe {
			val rotation = player.rotationClient.format(formatter)
			textCopyable(rotation)
		}
	}

@Jalvaviel I've removed your elytraflight changes as they did not work and ideally you should make a different pull request for this. I encourage you to speak with us on discord 👍
