Make NetworkTransform’s 0.001 GetChanged threshold configurable

[DavidSanek]

Hi Fish-Net team! 👋

We’ve hit a precision snag with NetworkTransform:

• In GetChanged() each axis is compared to a hard-coded 0.001f delta.
• Any movement smaller than that is ignored, so sub-millimetre motion (common in VR hand poses) never replicates and remote players see the glove frozen.
• Because the class is sealed, we can’t override the comparison; our only options are to patch the package file or maintain a full fork.

Propsal
Expose the threshold as a configurable field:

[SerializeField, Min(0f)]
private float positionEpsilon = 0.001f; // default = current behaviour

Replacing the four 0.001f literals with positionEpsilon lets projects dial in the precision they need without touching package code.
Alternatively, dropping sealed or making the comparer virtual would let us subclass and handle edge cases ourselves.

Thanks for the awesome networking stack!

This is reasonable and makes sense. It's no risk to anything to add in a threshold; I'm thinking this can be in the 4.6.10 release (no promises on that).
