Add package to npm for manual install in ReactNative

[rborn]

Hi,

The manual specify to add this package with yarn, however it will fail when trying to use it with npm

https://segment.com/docs/connections/sources/catalog/libraries/mobile/react-native/#dynamic-framework-for-manual-installation

So would be nice to have it working with npm too 😊

Thank you

We've got some major work planned for the RN library over the next few months. Will keep this warm until then. Thanks!!
