Not working on iPhone 5, iOS 10.3.4

Hello,
It took me a while to track down a bug, but it leads to your lib, as it's not working on iPhone 5/iOS 10.3.4

Here is the error output:

What's your React Native version?

[xseignard]

0.62.2

The plugin works on iPhone 6, iOS 12.3.4

Ugh. I've been able to reproduce this.

This is coming from iOS 10 and it must be related to the JavaScriptCore version being used as ArrayBuffer.prototype.byteLength is not defined. Everything is working fine on iOS 11.

Not sure how to fix this. 🤔

Maybe need a polyfill like the following

I would like to avoid the need of a polyfill, but it seems like this is coming from an issue within JavaScriptCore of iOS 10. So, we probably won't a choice here.

Polyfills are generally adding a significant footprint to the bundle size due to conditional imports not being supported, but I was able to find a good one here that seems high quality: https://polyfill.io/v3/polyfill.min.js?features=ArrayBuffer.

I'll retry with this later.

It's not working with those polyfills.

byteLength has to be an own property on the ArrayBuffer object, and in JavaScriptCore of iOS 10 and those polyfills, this is not the case.

Still investigating.

Fixed by #203 and will be released as 1.2.0-rc.1.
