[Bug] Inertia for pinchZoom jumpy on iOS

Description

When enabling inertia: true for the DeckGL controller, 2 finger pinch to zoom on iOS behaves very erraticly.
Particularly small pinches result in extreme jumps in zoom making the inertia option unusable with iOS Safari.

Flavors

• Script tag
• React
• Python/Jupyter notebook
• MapboxOverlay
• GoogleMapsOverlay
• CartoLayer
• ArcGIS

Expected Behavior

Pinching to zoom with inertia giving a smooth pinch to zoom experience without jumpy and erratic behaviour.

Steps to Reproduce

https://codepen.io/KaHole/pen/MWxYXep

1. Open Safari on iOS
2. Open project using inertia enabled controller, e.g. https://codepen.io/KaHole/pen/MWxYXep
3. Perform a couple of small 2 finger pinch to zoom gestures. (You may need to test for a while)
4. Observe the extreme jumps in zoom level that sometimes occur.

The issues arise with all kinds of pinches, but more frequently with small pinches.

Environment

• Framework version: 8.9.33
• Browser: iOS Safari
• OS: iOS 17.2.1

No response

Start by reproducing the issue in the linked CodePen on iOS Safari with the DeckGL controller's inertia enabled, using several small two-finger pinches. Trace the controller's pinch-zoom and inertia handling from that entry point. Done means small and large pinches produce smooth, stable zoom changes without extreme jumps on iOS Safari.
