[BUG] #69 regression (Overly-slow mouse scroll wheel)

[n00mkrad]

Describe the bug
Scrolling via mouse wheel is veeery, very slow. Refer to #69.
This was fixed in #88 but got broken again by Unity changing normalization to being the default in Unity 6000.0.9+.

This invalidated the compensation. The current package (7.1.0, f3d18ef) still includes the not-fix.

Workaround:
Have this run on startup: InputSystem.settings.scrollDeltaBehavior = InputSettings.ScrollDeltaBehavior.KeepPlatformSpecificInputRange;

To Reproduce
Steps to reproduce the behavior:

1. Make any scrollable uimgui
2. Scroll
3. Watch it be very slow

Version/Branch of UImGui:
Latest master (f3d18ef)

Unity Version
6000.3.21f1 (6.3 LTS)

Render pipeline (HDRP / URP / Built-in)
URP

Expected behavior
It should scroll at a reasonable speed. Not at 1-2 pixels per input.

Additional context

Proposed fix:

private static float ScrollWheelScale =>
#if UNITY_6000_0_OR_NEWER
    InputSystem.settings.scrollDeltaBehavior == InputSettings.ScrollDeltaBehavior.UniformAcrossAllPlatforms ? 1f : 1f / 120f;
#else
    1f / 120f;
#endif
