Pinch to zoom is slow and inaccurate

[aidanbae123]

Describe the bug
Pinch to zoom is almost unusably unresponsive and more often than not requires a second attempt to work normally. When it does zoom, it zooms very little and needs another motion to zoom further.

To Reproduce
Go onto any webpage and try to use the feature.

Expected behavior
Zoom should work as soon as trackpad motion is completed.

On a ThinkPad E14 G4 with the latest version of VoodooRMI and VoodooSMBUS.
ACPI settings:

        "ForceTouchType", 2,
        "TrackpointMultiplier", 30,
        "TrackpointScrollMultiplierX", 30,
        "TrackpointScrollMultiplierY", 30,
        "PalmRejectionWidth", 40,
        "MinYDiffThumbDetection", 100

Yeah I've ran into this too and it's probably related to how we number fingers if I had to guess. I'd be willing to accept PRs if anyone wants to attempt to fix this - the current code right now isn't great but the two places to look might be here and here. This file is where all the finger data is processed for VoodooInput and handles numbering fingers and doing palm rejection.
