onActive event needed to disable other gestures

[felix-phil]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch [email protected] for the project I'm working on.

I needed to know when pinching is active or not in order to disable all other gestures as the library is crashing iOS devices while pinching is active and other gestures are also active

Here is the diff that solved my problem:

@felix-phil , was curios whether this fully works or there are some issues in this patch

I currently use it on a production project. onActive prop to know when the pinch is going on so as to deactivate all other animation gestures. So, it works.
