Consider using react-native-quick-crypto

Hey!

I noticed this repo uses **react-native-crypto**, which itself uses **crypto-browserify** under the hood. **crypto-browserify** is a JS-based implementation for crypto, which is slower than Margelo's [**react-native-quick-crypto**](https://github.com/margelo/react-native-quick-crypto), since that uses C++ (OpenSSL) with JSI under the hood.

If you want to replace **react-native-crypto** with the faster **react-native-quick-crypto**, I'm happy to help out or answer questions! 😄

Start by locating the repository's use of react-native-crypto and its crypto-browserify dependency, then review react-native-quick-crypto's compatibility and setup requirements. Confirm the replacement works across the wallet's supported native platforms and compare the relevant crypto operations before considering the issue done.
