React Native - RN 0.60 support

ReactNative 0.60 introduced autolinking to link native modules through CocoaPods based on a podspec file. Currently, the Scandit ReactNative package is not distributed through CocoaPods, neither does it include a podspec file, so the autolinking process fails.

The SDK version 5.12 of the Scandit ReactNative package is providing a solution to this issue, so ReactNative is able to autolink the Scandit libraries that are necessary for the ReactNative package to work.

The next major 6.x Scandit SDK version of ReactNative will provide full CocoaPods support for both the native libraries and the ReactNative package, so it’ll be considerably easier to add our package to a ReactNative project.
