Expo support

[Jeremuelle]

Just a quick question, does this support expo?

I tried running the example but I'm getting an error

null is not an object (evaluating GPRNGeometryUtils.polygonContainsLocation)

Hello, I did not have experience with Expo but from what I understood Expo doesn't work with custom native modules.
I remember finding some pure JS libraries (non async) that do everything from this package.
I don't have access to the codebase where we used these geo util functions and I don't remember the name of those libraries, but I am sure that spending some time you will find the pure JS replacement for this library.

@dobrea-v, what pure JS libs for geo fencing are used in the @goparrot React Native app?
