Research and implement a solution that doesn't require a custom metro.config.js file when using react native SDK

Background

During our work with the React Native and Expo SDKs we had to configure the bundler to use browserify versions of certain libraries like crypto, stream, and randomBytes. This creates unnecessary additional configuration steps when starting to use our SDK and reduces the developer experience. More information here:

• https://github.com/affinityproject/affinidi-core-sdk/tree/master/sdk/react-native#mapping

What is needed to be done

Research and implement a solution that doesn't require any additional configuration besides npm install-ing the package. This could be in a form of different packages solving the problem or in a form of configuration being done during the installation phase (post-install hook?)

Why is this needed

We want to improve the developer experience of the developers using our SDK.
